Compression results computed from a set of six different `high-quality' datasets: mean structural similarity and standard deviation over compression ratios for the three different compression methods. Note that a compression ratio of up to about 4× is possible for all three codecs, as the similarity remains high with low variation. After this point, the quality deteriorates quickly for bit reset (red), but also, to a lesser degree, for the two transform-based methods (green and blue). |
