The symbol that actually occurs is encoded relative to its predicted distribution using arithmetic coding.
对于实际出现的符号，会使用算术编码，相对于其预测分发进行编码。

The current ROI coding methods either have high computational cost or cannot control the relative quality of progressive decoded images.
当前的ROI编码算法不能控制渐进解码图像的相对质量或是计算量太大。
3
The relative usage degree of the synonymous codon is computed and the use of preferences of the synonymous codon in 78 human genes (19967 codons) is analysed based on the quasi-amino acids coding.
