HDR-VDP-2 is relatively recent metric that produces predictions for difference visibility and quality degradation. http://sourceforge.net/apps/mediawiki/hdrvdp/index.php?title=Main_Page It could been interesting to add this metric in future studies.
Rafał Mantiuk (the guy behind HDR-VDP-2) also worked on this paper: "New Measurements Reveal Weaknesses of Image Quality Metrics in Evaluating Graphics Artifacts" http://www.mpi-inf.mpg.de/resources/hdr/iqm-evaluation/ Which leads to think that doing some blinded experiment (real people evaluating the images) to compare compressed images has still some value. It could be fun to conduct such an experience, presenting 2 or 3 versions of the same image compressed with different methods and asking a wide panel (could be open to anyone on the web) to pick their favorite one. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
