Abstract (EN): Computer analysis of objects¿ movement in image sequences is a very complex problem, as it usually involves tasks for automatic detection, matching, tracking and deformation estimation. However, this computational analysis has a wide range of important applications; for instance, in surveillance systems, clinical analysis of human gait, objects recognition and deformation analysis. Due to the extent of purposes, several difficulties may exist, such as the simultaneous tracking of multiple objects, their possible temporary occlusion or definitive disappearance from the scene, changes of the viewpoints considered in images acquisition or of the illumination conditions, or even geometric deformations that objects may suffer during the computational analysis. In this paper, we make a brief overview of several methods that may be considered to analyze objects¿ movement; namely, for their segmentation, tracking and matching in images, and for estimation of the deformation involved between images.
