Extraction des objets en mouvement : une approche mixte contours-régions

In this paper, we propose a new method to extract moving objects from a video stream without any motion estimation. The objective is to obtain a fast and efficient extraction method, robust to noise and large motions. Our approach consists in a frame differencing strategy combined with a hierarchical segmentation approach. First, we propose to extract moving edges with a new difference scheme, ...

Utilisation des relations spatiales pour l'analyse et l'édition de mouvement

Ondelettes et applications en imagerie et en calcul de surfaces

This thesis is a theorical and numerical contribution to wavelet transform in image processing and surface computing. Group theory approach, multiresolution approach and lters banc approach of wavelets basis are reviewed. The wavelet transform applications concern image compression, discrete curve representation and surface approximation by radial functions. We begin by reviewing di erent image...
