Paper Abstract

We present a two-step segmentation scheme for the very low bit rate coding of general purpose video scenes. Our objective is to determine the regions of interest before the actual segmentation procedure, so as to reduce the computational overhead introduced by this relatively complex process, and to avoid the phenomenon of over-segmentation of the scene. Simulation results show that the proposed scheme results in a radical reduction of the number of discrete spatio-temporal regions, while the background is identified as one uniform region, even when it is characterized by complex global motion.
