Paper Abstract

Video coding still remains a largely open problem after decades of research. In this paper, we present some new ideas of video coding from a geometric perspective. We focus on developing an improved modeling of video source by studying its geometric constraints. It is suggested that understanding the relationship between location uncertainty models of motion discontinuity and image singularity is critical to the efficiency of video coding. We argue that linearity is the root of problem in conventional motion compensated predictive coding and propose a classification-based nonlinear coding framework in both spatial and wavelet domains. Nonlinear processing tools are advocated for resolving location-related uncertainty during the exploitation of geometric constraints.
