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.
