Abstract

Previously (see Proc. ICIP, vol.1, p.542-5, 1995) we proposed a method for segmenting an image in a sequence of images into regions of stationary, moving, and uncovered background pixels and simultaneously estimating parameters of each region. This previous work focused on the viability of the idea and considered only moving and stationary pixels. In this paper we present an extension of the formulation to include uncovered background pixels and multiple object segmentation. We show segmentations and reconstructed image frames for synthetic image sequences
