Hi folks, here is another update of the new JPEG standard in the making. There is a new version of a proposal for this recent JPEG call here: https://github.com/thorfdbg/libjpeg.git Basically, what is new here is that there is an optional experimental noise-shaping algorithm enabled by -N which will better spread quantization errors in the HDR residual signal. As there is also a call from VESA for a high-speed online compression for video signals, I also tried to answer that and included a very slim variant of SPIHT for answering this call. It is a lossy to lossless compression algorithm operating only on lines, using the 5/3 wavelet and an un-encoded line version of SPIHT to compress (actually truncate, since there is no entropy coding) the signal. Works fairly well given its simplicity. I should also say that Guido Vollbeding (one and only member of IJG) seems to follow a different route and tries to establish a not-backwards compatible codec for HDR or lossless compression. Why that is a good idea (that is, to loose backwards compatibility, and *not* picking one of the existing standards in this area, e.g. JPEG LS or so) is beyond me. After all, there are already more than enough lossless/HDR image formats to pick from, and I don't see the need for another (non-compatible) one. But judge yourself...
