Optimization of Full Search Algorithm in AVS Encoding
Yuji Guo · Video Engineering · 2014
In this paper,digital audio and video encoding technology standard(Audio Video Coding Standard,AVS)is used asthe basis,by analysing the search algorithm of motion vector,to make improvements for the part of full search algorithm,propose and realize the pattern splicing technology to strengthen the relevance between the search mode,at the same timeavoid multiple searches on the same area. The new full search program can handle full search cif and D1 format videosequences. Compared with the old program,the new program keep rate and PSNR basically unchanged,the processing speedimproved 300%. It has important significance for hardware implementation.
