Video coding standard H.264/AVC employs zig-zag scan and field scan to map transform coefficients from two dimensional matrix to one dimensional array. The zig-zag scan is used for transform coefficients in frame macroblocks (MBs), and the field scan is used in field MBs. This paper presents a most probable scan mode (MPSM) decision for H.264 inter picture coding. Besides the two scans, a horizontal...
Video coding standard H.264/AVC employs nine-mode directional spatial prediction for intra picture coding. It predicts pixels to be encoded from previously decoded neighboring pixels within current picture. This paper presents an efficient coding method for H.264 intra picture prediction modes to enhance coding efficiency performance. The proposed method improves prediction of intra picture most probable...
