Thank you for publishing this study, here are my first questions: - Why didn't you include JPEG 2000?
- Correct me if I'm wrong but JPEG-XR native color space is not Y'CbCr this means that this format had to perform an extra (possibly lossy) color space conversion. - I suppose that the final lossless step used for JPEGs was the usual Huffman encoding and not arithmetic coding, have you considered testing the later one independently? - The image set is some what biased toward outdoor photographic images and highly contrasted artificial black and white ones, what about fractal renderings, operating systems and 2D/3D games screen-shots, blurry, out of frame or night shots? - I've found only two cats and not a single human face in the Tecnick image set, no fancy à la Instagram filters, this can't be seriously representative of web images, a larger image corpus would be welcome. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
