Title: A computer analysis of structures in image sequences : methods and applications
Issue Date: 2009
Abstract: The computer analysis of structures in image sequences is a very complex and challengingmatter as it usually involves automatic tasks for detection, matching, tracking, motionanalysis, deformation estimation as well as 3D shape reconstruction. Despite its inherentdifficulties, this computational analysis provides a wide range of important applications in oursociety such as is the case of medical diagnosis systems, surveillance systems, tools used todevelop virtual reality environments, biomechanical modeling, in addition to simulation andbioengineering systems.As a result of the extent of the purposes of this vast process, several difficulties can arise,such as is the case of the simultaneous analysis of manifold structures, cases of temporaryocclusion of the structure from the image scene or even its definitive disappearance,alterations of the viewpoints which have been taken into consideration or alternatively, of theillumination conditions, or even of the non-rigid deformations that non-rigid structures mayundergo along image sequences.In this presentation, we will provide an overview of several of the methods that we havedeveloped in order to analyze structures in image sequences; more specifically, those whichare used for the segmentation, tracking and matching of images, as well as the estimation ofthe deformation involved between images and the 3D shape reconstruction from images.Some application examples will be presented which take into consideration medical, face,traffic and surveillance images amongst others.
