In chapter four , first , the concept and basic flow of genetic algorithm is introduced , as well as a genetic algorithm based on variable length coding 第四章:首先介紹了遺傳算法概念及其基本流程,并對變長染色體遺傳算法作了一個簡要介紹。
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。
Based on the specialty of flexible processing enterprise , we designed and developed production planning system of processing err at last , a genetic algorithm based on variable length coding for the scroll cutting problem in production planning system is proposed 針對柔性流程企業(yè)生產(chǎn)計劃的特點,設計實現(xiàn)流程erp的排產(chǎn)計劃系統(tǒng),并提出了一種基于變長編碼遺傳算法以解決生產(chǎn)計劃中的紙卷切割問題。
Then some key techniques in mpeg - 2 and mpeg - 4 recommendations are studied and compared in detail , including motion estimation , motion compensation , discrete cosine transform , inverse discrete cosine transform , variable length coding and layered description of picture and code stream 然后深入研究了mpeg - 2建議的視頻編碼標準,包括ts流、 ps流、時鐘恢復、視頻與音頻的同步、基于場的運動補償、 dct及變長編碼。
Secondly , a software - based real - time h . 264 / avc is realized on x86 based ip stb by optimization for algorithms . based on the previous research of others , this dissertation implements an optimization of algorithm for motion compensation . context - adaptive variable length coding ( cavlc ) is chosen as entropy coding , a high 其次,本文討論了基于x86架構(gòu)ip機頂盒的h . 264解碼器的純軟件優(yōu)化問題,在參考相關(guān)資料的前提下,從算法角度實現(xiàn)了一種運動補償?shù)膬?yōu)化算法,以及一種基于分組的可變長快速cavlc熵解碼算法。
