Title: Adaptive Coding for Generalized Gaussian Sources in Image Coding
Abstract: Several latest video coding standards are introduced and compared. Since entropy coding is one of the most important topics that need serious study in the fields of video coding standards, the main work of this paper focuses on adaptive entropy coding. In this paper, an adaptive coding technique is proposed, namely, adaptive Exp-Golomb codes (AEG), in order to mitigate the efficiency loss due to mismatch. Analysis and simulations show that the adaptive techniques are robust enough to keep high coding efficiency (constantly about 90%) even if the sources undergo big changes.
