The general issue of our work is the elaboration of region-based active contours models for image and video segmentation. We propose to segment regions or objects by minimizing a general functional including domains and boundaries integrals. In this framework, the functions characterizing regions or boundaries are named "descriptors''. The minimum is searched using the propagation of a region-based active contour. The associated evolution equation is computed using shape derivation tools. Besides, we take into account the case of region-dependent descriptors that evolve during the curve propagation. We show that this variation induces supplementary terms in the evolution equation.<br /><br />Region-based active contours models are then appl...
