An algorithm for joint depth estimation and segmentation from multi-view images is presented.The distribution of the luminance of each image pixel is modeled as a random variable,which is approximated by a "mixture of Gaussians model". After recovering 3-D motion, a reference image is segmented into a fixed number of regions, each characterized by a distinct affine depth model with three parameters. The estimated depth parameters and segmentation masks are iteratively estimated using an Expectation-Maximization algorithm, similar to that proposed in [1 ]. In addition, the proposed algorithm is extended for cases where more than two images are available.
