摘要
在HEVC中CABAC的不同上下文模型,概率分配不同,采用恰当的初始概率值,有助于编码性能提升。为提高屏幕图像压缩性能,同济大学超大规模集成电路研究所在HEVC基础上提出了一种编码单元自适应双编码器,其CABAC部分与HEVC相同,文章主要对该双编码器进行初始概率值的研究与优化。
The entropy coding in HEVC is CABAC,its context model is adjusted and adapted through forecast.If proper initial probability is set,it could hence the encoding performance.For better dealing with Screen Images,VLSI in Tongji University proposes a coding unit adaptive dual-coder based on HEVC,it has the same CABAC part with HEVC,and this paper mainly researches and optimizes initial probability based on the dual-coder.
