Bitrate in lossless compression

Bitrate (bpp) for all tested lossless compression schemes. Results surrounded by underscores indicate lowest bitrate for a given object in a given table. In proposed compression the contribution of overflow/underflow information to the total rate is given in parentheses. It is given as part of total bitrate with values rounded up to whole order of magnitude. Combinations of codecs (C1-C5) are explained in the article.

所有待测无损压缩方案的比特率（bit per pixel，bpp）。表格中用下划线标注的结果，代表对应表格内特定对象的最低比特率。在本文提出的压缩方案中，溢出/下溢信息对总比特率的贡献以括号形式标注。该贡献计入总比特率，且数值已向上取整至整数量级。编解码器（codecs）组合（C1-C5）的详细说明详见本文。
