Paralelos do corpo

O objetivo deste trabalho foi à criação de um Curta-Metragem que causasse uma conexão com o espectador de forma mais sensorial e emotiva, amenizando compreensões racionais e lógicas. Para tal propósito foi utilizada uma representação, uma representação imagética de conceitos oriundos da Psicologia Jungiana, do Teatro da Crueldade e dos estudos de mitologia de Joseph Campbell. A computação gráfica foi utilizada na geração de elementos com o intuito de possibilitar a criação de uma simbologia fundamentada nas teorias pesquisadas. A tentativa de representação dos símbolos arquetípicos baseados nos estudos do Jung fundamentou a construção da obra final. Diversas técnicas foram aplicadas na produção do Curta-Metragem, como: Stop-motion, Foto-manipulação, Camera Tracking, Rotoscopia e Animação 3D. O estudo de composição de artistas que tenham a mesma linha temática possibilitou o melhor desenvolvimento da proposta.

O fantástico em Coraline: uma análise semiótica

The English writer Neil Gaiman has a varied background in various genres of literature and comics. His novel Coraline (2002) was considered a bestseller and received numerous adaptations, including versions for the comics (U.S., 2008, illustrated by P. Craig Russelle) and for a musical off Broadway (USA, 2009). The object of analysis chosen for this research was the adaptation of Coraline for film, Coraline (U.S., 2009), stop motion animation directed by Henry Selick. In the eyes of the general public the film stands out for being an engaging animation. Under a closer look, Coraline becomes a valuable object of study that incorporated the technique of stop motion at the same time that modernized the fantastic genre, usually directed to children and youth, but in that case, reaches many audiences. The objective of this research is to analyze the animation based on theory of origin greimasian, focusing on the narrative that constitutes the fantastic genre in order to infer the regularities of genrer and the specificities of audiovisual product

Targetless image-based method for measuring displacements and strains on concrete surfaces with a consumer camera

Measurement of concrete strain through non-invasive methods is of great importance in civil engineering and structural analysis. Traditional methods use laser speckle and high quality cameras that may result too expensive for many applications. Here we present a method for measuring concrete deformations with a standard reflex camera and image processing for tracking objects in the concretes surface. Two different approaches are presented here. In the first one, on-purpose objects are drawn on the surface, while on the second one we track small defects on the surface due to air bubbles in the hardening process. The method has been tested on a concrete sample under several loading/unloading cycles. A stop-motion sequence of the process has been captured and analyzed. Results have been successfully compared with the values given by a strain gauge. Accuracy of our methods in tracking objects is below 8 μm, in the order of more expensive commercial devices.

An investigation of thin film magnetic recording media

Mechanical, physical and chemical changes in the surface of commercial thin film metal evaporated magnetic recording media have been correlated to recording error and signal degradation measurements. Modified and adapted commercial Hi-8 video recorders have been used for sample generation whilst analytical techniques such as SXPS,IMS and SEM have been employed in the surface characterisation. The durability of the media was assessed through stop motion (still frame) and cycling tests, where error growth and signal degradation were measured as a function of running time. The tests were performed under ambient (22°C, 40% RH) and high humidity (22°C, 80% RH) conditions. Characterisation of the lubricant layer on each tape was performed through models based on XPS and angle resolved XPS. The lubricant thickness can significantly affect the durability and signal output level of a thin film tape and thus it is important that reliable quantification can be achieved. Various models were considered for determining the lubricant thickness although ultimately, the most suitable technique was deemed to be a model that assumed a uniform layer structure. In addition to thin film metal evaporated media, equivalent durability tests and surface analysis experiments were performed using a commercial metal particle tape in order that comparisons could be made between the two types of recording media. The signal performance of the thin film metal evaporated media was found to be quite different from that for the metal particle tape since dropout errors and signal degradation increased at a much earlier stage. Extensive surface analyses enabled the mechanisms responsible for media failure and error growth to be identified in the ME and MP tapes and these were found to result from cyclic stressing and fatigue on the immediate substrate of the media.

Intimité et sensations dans les films d'animation en volume de Girlin Bassovskaja

Peu satisfaite des concepts généralement mentionnés lorsqu’il s’agit d’écrire sur les films réalisés en stop-motion, je propose d’analyser un corpus de quatre films réalisés par un duo estonien peu connu, les réalisatrices Jelena Girlin et Mari-Liis Bassovskaja, en ancrant mon discours dans une recherche plus large sur l’intimité et la sensorialité en art. J’effleure, par l’entremise d’une revue de littérature, le paradoxe d’animer l’inanimé et l’idée du umheimlich freudien, prégnants dans les écrits substantiels autour du cinéma d’animation en volume. Après avoir démontré que l’œuvre de Girlin Bassovskaja s’incrit dans le domaine de l’intime, j’approfondis l’analyse en m’appuyant sur les théories de la visualité haptique appliquée aux films. Je découvre le corpus à la lumière de ces théories, et évoque l’idée du regard caressant du spectateur vers le film, mais aussi de sa réversibilité. De plus, en tant que réalisatrice-animatrice de court-métrages d’animation, les théories susmentionnées outillent ma pensée afin de décrire ma volonté quasi obsessionnelle de rendre l’intimité tangible par une animation sensuelle en pâte à modeler sur verre.

Documentário Animado: Representação da Memória em Narrativas Não Ficcionais

A animação surge enquanto técnica em narrativas não ficcionais no início do século XX, desvendando-se como um método eficaz para a representação de acontecimentos que se desvaneceram no tempo, e dos quais não há registo fotográfico ou vídeo. Logo, se essa representação tem por base indícios do real, pode-se classificar como documentário animado. Inicialmente a animação passou a desempenhar um papel importante na pedagogia e na propaganda, mas mais do que representar mimeticamente situações que não tiveram a oportunidade de serem captadas em live action, a animação demonstrou-se útil na esquematização de conceitos abstratos, tais como a memória. É neste sentido que foi pensado e desenvolvido o projeto Pronto, era assim consistindo numa curta-metragem documental, que tem como temática: o valor da terceira idade. O intuito do filme é enaltecer o contributo dos idosos na sociedade, e para isso contou-se com a gravação áudio das suas memórias e através da animação fez-se a sua representação. Pretendeu-se que as imagens não identificassem os entrevistados, mas sim, as histórias por elas relatadas e a sua personalidade.

The pedagogic prosthetic: Augmented learning as content-in-motion in hybrid educational spheres

This article draws on the design and implementation of three mobile learning projects introduced by Flanagan in 2011, 2012 and 2014 engaging a total of 206 participants. The latest of these projects is highlighted in this article. Two other projects provide additional examples of innovative strategies to engage mobile and cloud systems describing how electronic and mobile technology can help facilitate teaching and learning, assessment for learning and assessment as learning, and support communities of practice. The second section explains the theoretical premise supporting the implementation of technology and promulgates a hermeneutic phenomenological approach. The third section discusses mobility, both in terms of the exploration of wearable technology in the prototypes developed as a result of the projects, and the affordances of mobility within pedagogy. Finally the quantitative and qualitative methods in place to evaluate m-learning are explained.

Improved digital processing method used for image motion measurement based on hybrid opto-digital joint transform correlator

Hybrid opto-digital joint transform correlator (HODJTC) is effective for image motion measurement, but it is different from the traditional joint transform correlator because it only has one optical transform and the joint power spectrum is directly input into a digital processing unit to compute the image shift. The local cross-correlation image can be directly obtained by adopting a local Fourier transform operator. After the pixel-level location of cross-correlation peak is initially obtained, the up-sampling technique is introduced to relocate the peak in even higher accuracy. With signal-to-noise ratio >= 20 dB, up-sampling factor k >= 10 and the maximum image shift <= 60 pixels, the root-mean-square error of motion measurement accuracy can be controlled below 0.05 pixels.

Application of a hybrid tracking algorithm to motion analysis

An algorithm for tracking multiple feature positions in a dynamic image sequence is presented. This is achieved using a combination of two trajectory-based methods, with the resulting hybrid algorithm exhibiting the advantages of both. An optimizing exchange algorithm is described which enables short feature paths to be tracked without prior knowledge of the motion being studied. The resulting partial trajectories are then used to initialize a fast predictor algorithm which is capable of rapidly tracking multiple feature paths. As this predictor algorithm becomes tuned to the feature positions being tracked, it is shown how the location of occluded or poorly detected features can be predicted. The results of applying this tracking algorithm to data obtained from real-world scenes are then presented.

Projected equations of motion approach to hybrid quantum/classical dynamics in dielectric-metal composites

We introduce a hybrid method for dielectric-metal composites that describes the dynamics of the metallic system classically whilst retaining a quantum description of the dielectric. The time-dependent dipole moment of the classical system is mimicked by the introduction of projected equations of motion (PEOM) and the coupling between the two systems is achieved through an effective dipole-dipole interaction. To benchmark this method, we model a test system (semiconducting quantum dot-metal nanoparticle hybrid). We begin by examining the energy absorption rate, showing agreement between the PEOM method and the analytical rotating wave approximation (RWA) solution. We then investigate population inversion and show that the PEOM method provides an accurate model for the interaction under ultrashort pulse excitation where the traditional RWA breaks down.

Person tracking using motion detection and optical flow

Person tracking systems to date have either relied on motion detection or optical flow as a basis for person detection and tracking. As yet, systems have not been developed that utilise both these techniques. We propose a person tracking system that uses both, made possible by a novel hybrid optical flow-motion detection technique that we have developed. This provides the system with two methods of person detection, helping to avoid missed detections and the need to predict position, which can lead to errors in tracking and mistakes when handling occlusion situations. Our results show that our system is able to track people accurately, with an average error less than four pixels, and that our system outperforms the current CAVIAR benchmark system.

Object tracking using multiple motion modalities

This paper presents an object tracking system that utilises a hybrid multi-layer motion segmentation and optical flow algorithm. While many tracking systems seek to combine multiple modalities such as motion and depth or multiple inputs within a fusion system to improve tracking robustness, current systems have avoided the combination of motion and optical flow. This combination allows the use of multiple modes within the object detection stage. Consequently, different categories of objects, within motion or stationary, can be effectively detected utilising either optical flow, static foreground or active foreground information. The proposed system is evaluated using the ETISEO database and evaluation metrics and compared to a baseline system utilising a single mode foreground segmentation technique. Results demonstrate a significant improvement in tracking results can be made through the incorporation of the additional motion information.
