Klusterointi- japortfoliomenetelmien soveltaminen innovaatioprosessin alkupäässä

Työn tavoitteena on löytää menetelmä tai malli, jolla suurta joukkoa erilaatuisia ideoita pystytään lajittelemaan ja löytämään tästä joukosta relevantit ja parhaat ideat jatkoke-hittelyyn. Työn empiirisenä aineistona on käytetty kahdella eri toimialalla toimivan yrityksen yhteisessä ideaistunnossa syntyneitä ideoita. Työn teoreettisessa osuudessa on esitelty innovaation määritelmä sekä eri tapoja luoki-tella innovaatioita. Lisäksi teoreettisessa osuudessa on käsitelty avoimen innovaation periaatetta ja sen kenties yhä kasvavaa merkitystä. Työssä on käsitelty myös ideoiden hyödyntämiseen vaikuttavia seikkoja. Näkökulmiksi työssä on valittu yrityksen sisäiset ja ympäristöstä johtuvat seikat, kuten yrityksen osaaminen sekä asiakkaatja markkinat. Teoriaosuuden päättää lyhyt katsaus klusterointiin, sen eri menetelmiin, sekä portfolion hallintaan. Empiirisessä osuudessa yli 50 idean joukosta kyettiin löytämään muutamia ideoita, jotka ovat eri tavoilla toteutettavissa istuntoon osallistuneiden yritysten toimesta.

Innovaattorin dilemma - Kehittäminen vs. Parantaminen

Työssä tutkimme parantamis- ja kehittämisstrategiaa ja niiden yhteiskäyttöä eli ambidekstriaa. Tavoitteenamme on tuoda parantamis- ja kehittämisstrategian erot esille ja sijoittaa strategiat tuotteen elinkaarelle. Esittelemme organisaation ambidekstrian hallintaa ja vaikeuksia. Esittelemme ensin parantamis- ja kehittämisstrategian termit, eri innovaatiostrategiat ja tuotteen elinkaari mallit ja ambidekstrian kirjallisuuden pohjalta. Tämän jälkeen esittelemme case materiaalimme. Materiaalin pohjalta sijoitamme strategiat tuotteen elinkaarelle ja tuomme casessa esiintyneitä ambidekstrian ominaisuuksia esille. Tavoitteemme pohjalta voimme sanoa, että tuotteen elinkaaren vaiheilla ja parantamis- ja kehittämisstrategioilla on selvä yhteys ja strategiat sijoittuvat hyvin elinkaarelle. Ambidekstrian hallitseminen, eli parantamis- ja kehittämisstrategian tasapainon löytäminen ei ole helppoa, sillä strategiat ovat hyvin erilaisia keskenään. Hallinta vaatii paljon työtä, hyvän reagointikyvyn ja ennustamisen taidon, jotta yritys pysyy mukana muutoksessa ja mielellään hieman edellä, jos mielii teknologiajohtajaksi.

Model for managing non-core ideas to new companies, products and services in a Finnish forest company

Suomalainen metsäteollisuus on muutoksen partaalla. Uutisissa on nähty miten metsäyrityksen sulkevat tehtaita ja paperikoneita. Suomalaisessa metsäteollisuudessa keskitytään tällä hetkellä lähinnä kulujen alentamiseen ja tuottavuuden parantamiseen. Edellytyssille, että suomalainen metsäteollisuus pysyy kilpailukykyisenä, ovat kuitenkinuudet innovaatiot ja toimialojen välinen yhteistyö. Työn tavoitteena oli luoda toimintamalli UPM-Kymmene Oyj:lle, minkä avulla ydinliiketoimintaan kuulumattomat tuote- ja palveluideat saataisiin hyödynnettyä. Aihe on erittäin ajankohtainen, mikäli halutaan pitää tuotanto jatkossakin Suomessa. Luotumalli painottaa pk-sektorin roolia ja potentiaalia kehittää UPM-Kymmeneltä peräisin olevia ja heidän ydinliiketointaan kuulumattomista tuote ja palveluideoistauusia yrityksiä, tuotteita ja palveluita. Malli edustaa uudenlaista ajattelutapaa ja sen käyttöönotto vaatii perinteisen yrityskulttuurin uudistamista UPM-Kymmenessä.

Absorptive capacity and the effect of social integration mechanisms in knowledge utilization

Tiedosta on tullut määräävä tekijä yrityksensuorituskyvylle. Yritykset hankkivat aktiivisesti uutta tietoa ulkoisesta ympäristöstään ja tallentavat sitä tietokantoihinsa. Uusi tieto on innovaatioiden ja uusien ideoiden peruselementti. Uudet ideat pitää myös kaupallistaa, jotta niiden avulla voidaan hankkia kilpailuetua. Absorptiivisen kapasiteetin malli yhdistää tiedon prosessointiin liittyvät kyvykkyydet, jotka vaikuttavat yrityksen kykyyn hyödyntää tietoa tehokkaasti. Ennen kuin tietoa voidaan käyttää uusien tuotteiden ja palveluiden luomiseen, täytyy sitä jakaa yrityksessä ja muuttaa se yrityksen toimintaa palvelevaksi. Aiemmissa tutkimuksissa innovaatiot ovat vahvasti liitetty yrityksen kykyyn uudistua. Tämä pro gradu -tutkielma tutkii sosiaalisten integraatiomekanismien vaikutusta potentiaalisen absorptiivisen kapasiteetin muuttamiseen toteutuneeksi absorptiiviseksi kapasiteetiksi. Yksilöiden ja osastojen välisen yhteistyön sekä luottamuksen vaikutus tiedon sisäistämiseen tutkittiin. Tutkielma pohjautuu monikansallisessa yrityksessä keväällä 2006 suoritettuun uudistumiskyky-tutkimukseen. Tutkielma keskittyy yrityksen kykyyn uudistua uuden tiedon ja innovaatioiden avulla. Tutkielma on kvantitatiivinen tapaustutkimus. Tutkielmassa tehtyjen havaintojen mukaan sosiaaliset integraatiomekanismit ovat tärkeitä uuden tiedon hyödyntämisessä. Tiedon eksplisiittyyden havaitaan vaikuttavan tiedon muuttamiseen yritykselle hyödylliseksi resurssiksi.

Idea Screening in Telecom Business

Diplomityö on tehty Telecom Business Research Centerissä Lappeenrannassa. Toimialalle tyypillistä on tekniikan ja globaalien markkinoiden nopea kehitys, mikä edellyttää alan tuotekehitykseltä panostamista oikeisiin ideoihin, sekä niiden nopeaa ja joustavaa kehittämistä tuotteiksi. Tuotekehityksen alkuvaihe on johtamisen kannalta erityisen suuri haaste, koska ideoita on runsaasti, mutta resurssit tehdä niihin liittyviä selvityksiä ovat rajalliset. Diplomityön tavoitteena oli tuotekehityksen alkuvaiheen ymmärtäminen ja tutkia kuinka ideoita pystytään seulomaan. Tutkimus perustuu tuotekehityskirjallisuuteen ja haastatteluihin Telecom-teollisuudessa. Työn tuloksena ideoiden seulontaa kirjallisuudessa ja Telecom-teollisuudessa kuvataan ja niiden perusteella esitetään toimivia käytäntöjä tuotekehitysideoiden seulontaan toimialalla. Ehdotettujen käytäntöjen tavoitteena on saada parempia ideoita tehokkaammin tuotekehityksen alkuvaiheesta varsinaiseksi tuotekehitysprojektiksi.

Dialogue in the crisis of representation : realism and antirealism in the context of the conversation between theologians and quantum physicists in Göttingen 1949-1961

The aim of this study is to analyse the content of the interdisciplinary conversations in Göttingen between 1949 and 1961. The task is to compare models for describing reality presented by quantum physicists and theologians. Descriptions of reality indifferent disciplines are conditioned by the development of the concept of reality in philosophy, physics and theology. Our basic problem is stated in the question: How is it possible for the intramental image to match the external object?Cartesian knowledge presupposes clear and distinct ideas in the mind prior to observation resulting in a true correspondence between the observed object and the cogitative observing subject. The Kantian synthesis between rationalism and empiricism emphasises an extended character of representation. The human mind is not a passive receiver of external information, but is actively construing intramental representations of external reality in the epistemological process. Heidegger's aim was to reach a more primordial mode of understanding reality than what is possible in the Cartesian Subject-Object distinction. In Heidegger's philosophy, ontology as being-in-the-world is prior to knowledge concerning being. Ontology can be grasped only in the totality of being (Dasein), not only as an object of reflection and perception. According to Bohr, quantum mechanics introduces an irreducible loss in representation, which classically understood is a deficiency in knowledge. The conflicting aspects (particle and wave pictures) in our comprehension of physical reality, cannot be completely accommodated into an entire and coherent model of reality. What Bohr rejects is not realism, but the classical Einsteinian version of it. By the use of complementary descriptions, Bohr tries to save a fundamentally realistic position. The fundamental question in Barthian theology is the problem of God as an object of theological discourse. Dialectics is Barth¿s way to express knowledge of God avoiding a speculative theology and a human-centred religious self-consciousness. In Barthian theology, the human capacity for knowledge, independently of revelation, is insufficient to comprehend the being of God. Our knowledge of God is real knowledge in revelation and our words are made to correspond with the divine reality in an analogy of faith. The point of the Bultmannian demythologising programme was to claim the real existence of God beyond our faculties. We cannot simply define God as a human ideal of existence or a focus of values. The theological programme of Bultmann emphasised the notion that we can talk meaningfully of God only insofar as we have existential experience of his intervention. Common to all these twentieth century philosophical, physical and theological positions, is a form of anti-Cartesianism. Consequently, in regard to their epistemology, they can be labelled antirealist. This common insight also made it possible to find a common meeting point between the different disciplines. In this study, the different standpoints from all three areas and the conversations in Göttingen are analysed in the frameworkof realism/antirealism. One of the first tasks in the Göttingen conversations was to analyse the nature of the likeness between the complementary structures inquantum physics introduced by Niels Bohr and the dialectical forms in the Barthian doctrine of God. The reaction against epistemological Cartesianism, metaphysics of substance and deterministic description of reality was the common point of departure for theologians and physicists in the Göttingen discussions. In his complementarity, Bohr anticipated the crossing of traditional epistemic boundaries and the generalisation of epistemological strategies by introducing interpretative procedures across various disciplines.

Building organizational creativity – a multitheory and multilevel approach for understanding and stimulating organizational creativity

Organizational creativity is increasingly important for organizations aiming to survive and thrive in complex and unexpectedly changing environments. It is precondition of innovation and a driver of an organization’s performance success. Whereas innovation research increasingly promotes high-involvement and participatory innovation, the models of organizational creativity are still mainly based on an individual-creativity view. Likewise, the definitions of organizational creativity and innovation are somewhat equal, and they are used as interchangeable constructs, while on the other hand they are seen as different constructs. Creativity is seen as generation of novel and useful ideas, whereas innovation is seen as the implementation of these ideas. The research streams of innovation and organizational creativity seem to be advancing somewhat separately, although together they could provide many synergy advantages. Thereby, this study addresses three main research gaps. First, as the knowledge and knowing is being increasingly expertized and distributed in organizations, the conceptualization of organizational creativity needs to face that perspective, rather than relying on the individual-creativity view. Thus, the conceptualization of organizational creativity needs clarification, especially as an organizational-level phenomenon (i.e., creativity by an organization). Second, approaches to consciously build organizational creativity to increase the capacity of an organization to demonstrate novelty in its knowledgeable actions are rare. The current creativity techniques are mainly based on individual-creativity views, and they mainly focus on the occasional problem-solving cases among a limited number of individuals, whereas, the development of collective creativity and creativity by the organization lacks approaches. Third, in terms of organizational creativity as a collective phenomenon, the engagement, contributions, and participation of organizational members into activities of common meaning creation are more important than the individualcreativity skills. Therefore, the development approaches to foster creativity as social, emerging, embodied, and collective creativity are needed to complement the current creativity techniques. To address these gaps, the study takes a multiparadigm perspective to face the following three objectives. The first objective of this study is to clarify and extend the conceptualization of organizational creativity. The second is to study the development of organizational creativity. The third is to explore how an improvisational theater based approach fosters organizational creativity. The study consists of two parts comprising the introductory part (part I) and six publications (part II). Each publication addresses the research questions of the thesis through detailed subquestions. The study makes three main contributions to the research of organizational creativity. First, it contributes toward the conceptualization of organizational creativity by extending the current view of organizational creativity. This study views organizational creativity as a multilevel construct constituting both of individual and collective (group and organizational) creativity. In contrast to current views of organizational creativity, this study bases on organizational (collective) knowledge that is based on and demonstrated through the knowledgeable actions of an organization as a whole. The study defines organizational creativity as an overall ability of an organization to demonstrate novelty in its knowledgeable actions (through what it does and how it does what it does).Second, this study contributes toward the development of organizational creativity as multi-level phenomena, introducing developmental approaches that face two or more of these levels simultaneously. More specifically, the study presents the cross-level approaches to building organizational creativity, by using an approach based in improvisational theater and considering assessment of organizational renewal capability. Third, the study contributes on development of organizational creativity using an improvisational theater based approach as twofold meaning. First, it fosters individual and collective creativity simultaneously and builds space for creativity to occur. Second, it models collective and distributed creativity processes, thereby, contributing to the conceptualization of organizational creativity.

Comparison and problems between Traditional and Agile software development methods

In today’s world because of the rapid advancement in the field of technology and business, the requirements are not clear, and they are changing continuously in the development process. Due to those changes in the requirements the software development becomes very difficult. Use of traditional software development methods such as waterfall method is not a good option, as the traditional software development methods are not flexible to requirements and the software can be late and over budget. For developing high quality software that satisfies the customer, the organizations can use software development methods, such as agile methods which are flexible to change requirements at any stage in the development process. The agile methods are iterative and incremental methods that can accelerate the delivery of the initial business values through the continuous planning and feedback, and there is close communication between the customer and developers. The main purpose of the current thesis is to find out the problems in traditional software development and to show how agile methods reduced those problems in software development. The study also focuses the different success factors of agile methods, the success rate of agile projects and comparison between traditional and agile software development.

Organizing for Systemic Innovations – Research on Knowledge, Interaction and Organizational Interdependencies

Systemic innovation has emerged as an important topic due to the interconnected technological and sociotechnical change of our current complex world. This study approaches the phenomenon from an organizing perspective, by analyzing the various actors, collaborative activities and resources available in innovation systems. It presents knowledge production for innovation and discusses the organizational challenges of shared innovation activities from a dynamic perspective. Knowledge, interaction, and organizational interdependencies are seen as the core elements of organizing for systemic innovations. This dissertation is divided into two parts. The first part introduces the focus of the study and the relevant literature and summarizes conclusions. The second part includes seven publications, each reporting on an important aspect of the phenomenon studied. Each of the in-depth single-case studies takes a distinct and complementary systems approach to innovation activities – linking the refining of knowledge to the enabling of organizations to participate in shared innovation processes. These aspects are summarized as theoretical and practical implications for recognizing innovation opportunities and turning ideas into innovations by means of using information and organizing activities in an efficient manner. Through its investigation of the existing literature and empirical case studies, this study makes three main contributions. First, it describes the challenges inherent in utilizing information and transforming it into innovation knowledge. Secondly, it presents the role of interaction and organizational interdependencies in innovation activities from various novel perspectives. Third, it highlights the interconnection between innovations and organizations, and the related path dependency and anticipatory aspects in innovation activities. In general, the thesis adds to our knowledge of how different aspects of systems form innovations through interaction and organizational interdependencies. It highlights the continuous need to redefine information and adjust organizations and networks based on ongoing activities – stressing the emergent, systemic nature of innovation.

Collectiveness within startup teams – Leading the way to initiating and managing collective pursuit of opportunities in organizational contexts

While traditional entrepreneurship literature addresses the pursuit of entrepreneurial opportunities to a solo entrepreneur, scholars increasingly agree that new ventures are often founded and operated by entrepreneurial teams as collective efforts especially in hightechnology industries. Researchers also suggest that team ventures are more likely to survive and succeed than ventures founded by the individual entrepreneur although specific challenges might relate to multiple individuals being involved in joint entrepreneurial action. In addition to new ventures, entrepreneurial teams are seen central for organizing work in established organizations since the teams are able to create major product and service innovations that drive organizational success. Acknowledgement of the entrepreneurial teams in various organizational contexts has challenged the notion on the individual entrepreneur. However, considering that entrepreneurial teams represent a collective-level phenomenon that bases on interactions between organizational members, entrepreneurial teams may not have been studied as indepth as could be expected from the point of view of the team-level, rather than the individual or the individuals in the team. Many entrepreneurial team studies adopt the individualized view of entrepreneurship and examine the team members’ aggregate characteristics or the role of a lead entrepreneur. The previous understandings might not offer a comprehensive and indepth enough understanding of collectiveness within entrepreneurial teams and team venture performance that often relates to the team-level issues in particular. In addition, as the collective-level of entrepreneurial teams has been approached in various ways in the existing literatures, the phenomenon has been difficult to understand in research and practice. Hence, there is a need to understand entrepreneurial teams at the collective-level through a systematic and comprehensive perspective. This study takes part in the discussions on entrepreneurial teams. The overall objective of this study is to offer a description and understanding of collectiveness within entrepreneurial teams beyond individual(s). The research questions of the study are: 1) what collectiveness within entrepreneurial teams stands for, what constitutes the basic elements of it, and who are included in it, 2) why, how, and when collectiveness emerges or reinforces within entrepreneurial teams, and 3) why collectiveness within entrepreneurial teams matters and how it could be developed or supported. In order to answer the above questions, this study bases on three approaches, two set of empirical data, two analysis techniques, and conceptual study. The first data set consists of 12 qualitative semi-structured interviews with business school students who are seen as prospective entrepreneurs. The data is approached through a social constructionist perspective and analyzed through discourse analysis. The second data set bases on a qualitative multiplecase study approach that aims at theory elaboration. The main data consists of 14 individual and four group semi-structured thematic interviews with members of core entrepreneurial teams of four team startups in high-technology industries. The secondary data includes publicly available documents. This data set is approached through a critical realist perspective and analyzed through systematic thematic analysis. The study is completed through a conceptual study that aims at building a theoretical model of collective-level entrepreneurship drawing from existing literatures on organizational theory and social-psychology. The theoretical work applies a positivist perspective. This study consists of two parts. The first part includes an overview that introduces the research background, knowledge gaps and objectives, research strategy, and key concepts. It also outlines the existing knowledge of entrepreneurial team literature, presents and justifies the choices of paradigms and methods, summarizes the publications, and synthesizes the findings through answering the above mentioned research questions. The second part consists of five publications that address independent research questions but all enable to answer the research questions set for this study as a whole. The findings of this study suggest a map of relevant concepts and their relationships that help grasp collectiveness within entrepreneurial teams. The analyses conducted in the publications suggest that collectiveness within entrepreneurial teams stands for cognitive and affective structures in-between team members including elements of collective entity, collective idea of business, collective effort, collective attitudes and motivations, and collective feelings. Collectiveness within entrepreneurial teams also stands for specific joint entrepreneurial action components in which the structures are constructed. The action components reflect equality and democracy, and open and direct communication in particular. Collectiveness emerges because it is a powerful tool for overcoming individualized barriers to entrepreneurship and due to collectively oriented desire for, collective value orientation to, demand for, and encouragement to team entrepreneurship. Collectiveness emerges and reinforces in processes of joint creation and realization of entrepreneurial opportunities including joint analysis and planning of the opportunities and strategies, decision-making and realization of the opportunities, and evaluation, feedback, and sanctions of entrepreneurial action. Collectiveness matters because it is relevant for potential future entrepreneurs and because it affects the ways collective ventures are initiated and managed. Collectiveness also matters because it is a versatile, dynamic, and malleable phenomenon and the ideas of it can be applied across organizational contexts that require team work in discovering or creating and realizing new opportunities. This study further discusses how the findings add to the existing knowledge of entrepreneurial team literature and how the ideas can be applied in educational, managerial, and policy contexts.

A human-centric service approach for architecting and reengineering global system

Production of a new system in any range is expanding dramatically and new ideas are there upon introduced, the logic stands behind the matter is the growth of application of the internet and granting web-based systems. Before producing a system and distribute to the customer, various aspects should be studied which multiple the profit of the system. The process of productizing a new system from being unprocessed idea until delivers to the final user has been unambiguous. In this thesis, the systematize service in a way that benefits both the customer and provider, along with an effort to establish trust and diminish customer’s risk and increase service productivity are in detail presented. Characteristics of Servitization and Productization as two faces of one coin have been interpreted. Apart from the abovementioned issues state of art, service-oriented architecture (SOA) and New Service Development (NSD) has been included in this report for solving the problem of gradually decline in value of companies.

Development of business processes and sales reporting - Case recovered paper

The purpose of this research is to discover development points for business processes and sales reporting in the recovered paper sourcing organization. The processes under development are both sales and sourcing processes that were determined by the commissioning company. All of these processes have in common that there are used sales orders to organize the money flows correctly. Although the main objective is to source only recovered paper, the sourcing also brings by-products that cannot be utilized and are thus sold. As the purpose of the sales function is to only support the sourcing strategy, it should be organized as efficiently as possible. Investigating the current status of the processes and finding development points help in building proposals for enhanced process descriptions. In order that sales function could be analyzed, should the sales reporting be accurate and present the needed key figures. The current status of the processes as well as the possible problems and development ideas were researched with the help of interviews. Best practices could also be brought from other business lines in the commissioning company. The theory part was build according to relevant literature and scientific articles. The research indicates, that processes have shaped differently in sourcing organization’s business units. Local infrastructure and legislation sets certain limitations to the sourcing of recovered paper, and these circumstances cannot be changed. Customer-supplier power relations also affect to the formulation of business processes. In order to steer the processes, there has to be more internal controls. Still, the enterprise resource planning system also sets boundaries how the processes can be made more efficient.

Organisaation uudistumiskyvyn kehittäminen, Case: Stora Enso

Tutkielman tavoitteena oli selvittää case-organisaatio Stora Enson Anjalan paperitehtaan uudistumiskyky, toiminnan strategianmukaisuus sekä vahvuudet ja kehitettävät osa-alueetuudistumiskyvyssä. Tutkielmassa käytettiin kvantitatiivista tutkimusotetta. Aineisto kerättiin kahdella eri mittarilla: KM-Factor¿ ¿ uudistumiskyvyn mittarilla ja organisaation muutoskyvyn mittarilla. KM-Factor¿ ¿mittarin avulla kerättiin tietoa organisaation suhteiden, tiedonkulun, osaamisen ja johtamisen nyky- ja tavoitetilasta erilaisissa tietoympäristöissä. Muutoskyvyn mittarin avulla kerättiin tietoa organisaation uudistumiskyvystä kuuden sitä kuvaavan ominaisuuden, strategisen kyvykkyyden, johtajuuden, ajan hyödyntämisen, verkostoituneisuuden, tiedon johtamisen ja oppimissuuntautuneisuuden perusteella. Mittaukset suoritettiin helmikuussa 2006 ja niiden kohteena oli Stora Enson Anjalan paperitehtaan koko henkilöstö. Kahden uudistumiskyvyn mittarin tulokset analysoitiin ja niitä vertailtiin keskenään. Tällä tavalla pyrittiinmyös lisäämään tutkimuksen validiteettia. Mittaustulokset purettiin sanalliseenmuotoon ja niistä raportoitiin case-organisaatiolle. Mittausten mukaan case-organisaation uudistumiskyky oli hieman keskitasoa heikompi. Toiminnan vahvuuksia olivat yksimielisyys muutostarpeista ja tilanneherkkyys. Merkittävimmät toiminnan heikkoudet löytyivät nykyisestä toimintatavasta, joka ei ollut strategian mukainen, ja innovaatiopotentiaalista, joka oli hyvin alhainen. Kehittämisen tarpeita löytyi sekä johdon että henkilöstön suhteiden ja yhteistyön osalta. Koko organisaation tulisi lisätä yhteistyötä ulkopuolisten tahojen ja sidosryhmien kanssa. Organisaatiossa tulisi miettiä, miten strategia saataisiin selkeästi viestittyä myös johtoa alemmille tasoille. Johto painotti liikaa autoritääristä johtamista, kun taas henkilöstöltä odotettaisiin enemmän vastuunottoa toiminnastaan. Organisaatiossa tulisi saada nykyistä avoimemmin ja itsenäisemmin ilmaista omia näkemyksiään, toimia aloitteellisesti ja luoda uusia ideoita toiminnan kehittämiseksi. Innovatiivisuudesta ja parannusehdotuksista tulisi myös palkita paremmin.

Distance Transforms on Gray-Level Surfaces

This thesis studies gray-level distance transforms, particularly the Distance Transform on Curved Space (DTOCS). The transform is produced by calculating distances on a gray-level surface. The DTOCS is improved by definingmore accurate local distances, and developing a faster transformation algorithm. The Optimal DTOCS enhances the locally Euclidean Weighted DTOCS (WDTOCS) with local distance coefficients, which minimize the maximum error from the Euclideandistance in the image plane, and produce more accurate global distance values.Convergence properties of the traditional mask operation, or sequential localtransformation, and the ordered propagation approach are analyzed, and compared to the new efficient priority pixel queue algorithm. The Route DTOCS algorithmdeveloped in this work can be used to find and visualize shortest routes between two points, or two point sets, along a varying height surface. In a digital image, there can be several paths sharing the same minimal length, and the Route DTOCS visualizes them all. A single optimal path can be extracted from the route set using a simple backtracking algorithm. A new extension of the priority pixel queue algorithm produces the nearest neighbor transform, or Voronoi or Dirichlet tessellation, simultaneously with the distance map. The transformation divides the image into regions so that each pixel belongs to the region surrounding the reference point, which is nearest according to the distance definition used. Applications and application ideas for the DTOCS and its extensions are presented, including obstacle avoidance, image compression and surface roughness evaluation.
