A GUI for a Software that Analyses a Composite Bolted Joint

FastComp is a computational tool for the determination of the forces that a composite bolted joint subjected to multiaxial loads supports until failure occurs. The main intention of the present work was the development of a graphical user interface (GUI) for the referred tool that allows its parameterization and the visualization of its output results. Using VTK – The Visualization Toolkit, a computationa...

Segmentation of objects in images using physical principles

The final goal of this work is to automatically extract the contour of an object represented in an image after manually defining an initial contour for it. This rough initial contour will then evolve until it equals the border of the desired object. The contour is modelled by a physical formulation, using the Finite Element Method, and its evolution to the desired final contour of the object to segment is gover...

Determination of objects contours using physical principles

Segmentation and Simulation of Objects in Pedobarography images using Physical ...

The goals of the present work are to automatically extract the contour of an object and to simulate its deformation using a physical approach. Thus, to segment an object represented in an image, an initial contour is manually defined for it that will then automatically evolve until it equals the border of the desired object. The contour is modelled by a physical formulation, and its evolution to the desired fin...

The goal of this work is to automatically extract the contour of an object and to simulate its deformation using a physical approach. In this work, to segment an object represented in an image, an initial contour is manually defined for it that will then automatically evolve until it equals the border of the desired object. In our approach, the contour is modelled by physical formulation, using the Finite Eleme...

Segmentação e Simulação de Contornos em Imagens através de Processos Físicos

O objectivo principal deste trabalho é, a partir de duas imagens de um mesmo objecto em dois instantes distintos, simular as formas intermédias que o objecto assume quando o seu comportamento é guiado por princípios físicos. Para tal, é preciso começar por segmentar o objecto nas duas imagens em questão extraindo o seu contorno, após definição manual de um contorno inicial em cada uma delas. Seguidamente, cada ...

Using Physical Principles in the Segmentation of Objects Represented in Images

Usually, image segmentation is the first high-level task to extract information from an image, which can constitute one of the first steps to build a solid model of an organ and other structures of the human body, for example. Region segmentation distinguishes different areas of an image, and contour segmentation delimits the different regions by their frontiers. The main goal of this work is to extract the con...

The main goals of the present work are to automatically extract the contour of an object and to simulate its deformation using a physical approach. In this work, to seg-ment an object represented in an image, an initial contour is manually defined for it that will then automatically evolve until it reaches the border of the desired object. In this ap-proach, the contour is modelled by a physical formulation usi...

Segmentação de Objectos Representados em Imagens Segundo Princípios Físicos

O objectivo principal deste trabalho é extrair o contorno de um objecto representado numa imagem após definir um contorno inicial para este; posteriormente, este contorno irá evoluir na imagem até à fronteira do objecto em causa. O contorno do objecto é neste trabalho modelado através de uma formulação física, usando o método dos elementos finitos, e a sua evolução temporal é devida à existência de forças inter...
