I hope evaluation will use more diverse set of images than the subset given. Only a couple of example images have highly saturated color, and all example images will tolerate poorly done chroma subsampling.<p>On the web there are categories of images, such as logos, screenshots, renders, large icons, photos with captions, that aren&#x27;t simple enough to compress well with lossless encoders, but become a mess when compressed with codecs tuned for high-res photos without any sharp highly saturated edges.
