Context - based adaptive binary arithmetic coding ( cabac ) has been a normative scheme of entropy coding in video coding standards such as h . 264 , avs , for its excellent coding efficiency 基于上下文的自適應二進制算術編碼( cabac )以其高效的編碼優(yōu)勢,被h . 264 、 avs等視頻標準紛紛采用,成為主要的熵編碼方案。
138 variable length coding ( vlc ) : a reversible procedure for entropy coding that assigns shorter bit strings to symbols expected to be more frequent and longer bit strings to symbols expected to be less frequent 可變長編碼vlc :一種可逆熵編碼,為出現(xiàn)頻率高的符號分配少的位,為出現(xiàn)頻率低的符號更多的位。
To solve the above - mentioned two problems , this paper proposes a multiple description video coding method based on 3d - dct and mdsq . the system consists of several parts : video volume formation , 3d - dct , mdsq , rle coding and entropy coding and so on 針對上述兩個問題,本文提出基于3d - dct的多描述編碼方案,它由分塊、 3d - dct變換、量化、 mdsq編碼、 rle編碼和熵編碼等部分組成。
This thesis gives an overview of entropy coding in jpeg 2000 , especially the code - block based coding and context based adaptive arithmetic coding . to optimize the implementation of mq encoder , several methods are adopted to optimize the algorithm which is emulated in matlab 因此本文對jpeg2000標準中位平面編碼和基于上下文的自適應二進制算術編碼技術作了詳細的分析和研究之后,對自適應算術編碼算法優(yōu)化使其更適合于硬件實現(xiàn)。
