Maybe someone here will know of a website that describes each step of the jpeg xl format in detail? Unlike for traditional jpeg, I have found it hard to find a document providing clear instructions on the relevant steps, which is a shame as there are clearly tons of interesting innovations that have been compiled together to make this happen, and I'm sure the individual components are useful in their own right!
- adgjlsfhk1 3y agohttps://github.com/libjxl/libjxl/blob/main/doc/format_overview.md https://github.com/libjxl/libjxl/blob/main/doc/format_overvi... is a pretty detailed but good overview. The highlights are variable size DCT (up to 128x128), ANS entropy prediction, and chroma from luminance prediction. https://github.com/libjxl/libjxl/blob/main/doc/encode_effort.md https://github.com/libjxl/libjxl/blob/main/doc/encode_effort... also gives a good breakdown of features by effort level.
