Abstract :
In this paper, we investigate some recent active contour models used in image and video segmentation and we transpose them into a discrete form to apply the iterated conditional modes (ICM) algorithm. This work can be seen as an extension of the recent work of T. Chan and B. Song for other functional than the Mumford-Shah/Chan-Vese one. We investigate it for video segmentation and tracking applications.
