Abstract :
In this paper, novel intra prediction methods based on image inpainting approaches are proposed. The H.264/AVC intra prediction modes are not well suited for processing complex textures at low bit rates. Our algorithm utilizes an efficient combination of partial differential equations (PDEs) and patch-based texture synthesis in addition to the standard directional predictors. Bit rate savings up to 3.5% compared to that of the H.264/AVC standard are shown.
