Processamento de imagem digital para o controlo de qualidade do queijo regional de Évora

A utilização generalizada do computador para a automatização das mais diversas tarefas, tem conduzido ao desenvolvimento de aplicações que possibilitam a realização de actividades que até então poderiam não só ser demoradas, como estar sujeitas a erros inerentes à actividade humana. A investigação desenvolvida no âmbito desta tese, tem como objectivo o desenvolvimento de um software e algoritmos que permitam a avaliação e classificação de queijos produzidos na região de Évora, através do processamento de imagens digitais. No decurso desta investigação, foram desenvolvidos algoritmos e metodologias que permitem a identificação dos olhos e dimensões do queijo, a presença de textura na parte exterior do queijo, assim como características relativas à cor do mesmo, permitindo que com base nestes parâmetros possa ser efectuada uma classificação e avaliação do queijo. A aplicação de software, resultou num produto de simples utilização. As fotografias devem respeitar algumas regras simples, sobre as quais se efectuará o processamento e classificação do queijo. ABSTRACT: The widespread use of computers for the automation of repetitive tasks, has resulted in developing applications that allow a range of activities, that until now could not only be time consuming and also subject to errors inherent to human activity, to be performed without or with little human intervention. The research carried out within this thesis, aims to develop a software application and algorithms that enable the assessment and classification of cheeses produced in the region of Évora, by digital images processing. Throughout this research, algorithms and methodologies have been developed that allow the identification of the cheese eyes, the dimensions of the cheese, the presence of texture on the outside of cheese, as well as an analysis of the color, so that, based on these parameters, a classification and evaluation of the cheese can be conducted. The developed software application, is product simple to use, requiring no special computer knowledge. Requires only the acquisition of the photographs following a simple set of rules, based on which it will do the processing and classification of cheese.

This report aims to present the experience lived in the project "The School Pedro II in the Professional Decision of Secondary Education Students" aimed to promote professional student choice for the preparation of secondary to higher education, technical or job market with the integration of the areas of knowledge and ICT. Starting questions: How to awaken in students a vocation for academic life? How establish the connection between what students want to be in the future and to choose when isn’t a university course? How to take into account the factors that interfere in making professional student decision to build his own knowledge about your chosen profession? The experiment was performed at the State School of Elementary and Secondary Education D. Pedro II (Belem of Para State/Brazil), based on the view that knowledge must be represented in a format that requires coordination with the different forms of knowledge and the organization and use of technology. The results show that the tasks performed by students for professional choice provided information about themselves and the professional world. The conceptual map has contributed as a mediating tool of the teaching, learning and assessment and favored interest, autonomy and participation.
