I also read on a few other forums users' opinions of jpegmini. Extremely handy! I only wish it showed more of the tool's internal options. I used to have a script for compressing PNGs with PNGOUT but now RIOT allows to process them in batch. I tried the tool the user posted on this thread but it produced some weird results, on a few images it cropped the picture by a few pixels. Messing with the Chroma and Luma channels is something nearly every jpeg compressing tool does and I'd like to know which one I'm using to compare their features. I liked RIOT very much but I wish it showed which external tools it uses besides the PNG ones. Hopefully being open source means others will step up with with cool new ideas. I'm sure there are a ton of optimizations to be made, but to be totally honest my math and C programming skills are not the best. if it's a picture of clouds then lower the quality slightly and if it's an intricate building then increase the quality a bit. One thing I would like to add is some measure of overall image complexity, e.g. what's the average pixel value, how do the pixels vary, what's the relationship between the original variance and the reference block variance, etc. The algorithm I use is SSIM, which works by measuring relationships between pixels in 8x8 blocks, e.g. I haven't read the patents (and won't due to possibly tainting my own code with information from them). JPEGmini actually uses some custom patented algorithm for perceived image quality. That's much better than throwing away too much. Luckily it errs on the side of caution and throws away less data than JPEGmini. I think the groups of solid colors are problematic.
