| 1. | The unary code is applied in the binarization of the translation coefficients in the national standard avs . it is preponderant for the small values , but will bring more redundancy for the bigger ones . so the exp - golomb code is introduced for the redundancy reduction 在avs标准中,变换系数level值的二值化方案采用了unary码, unary码对较小的整数值二值化效果较好,但对较大的值则会造成很大的冗余,从而影响了cabac的编码效率。 |
