Have you played with Mozjpeg? (image optimization)

RE: Have you played with Mozjpeg? (image optimization)
Hey avalanch,

Yeah .. they use a patent-pending algorithm to change the quantification tables somehow.
I think they change the q-tables on the fly and select the best tables by analyzing the image and choosing to use high quality compression in areas where the eye is likely to be watching, and low quality compression where the eye won't look.

So, this is kinda like how mozjpeg is doing things, but it seems to go further than mozjpeg.

It's kinda like if you would mix Kornel's dssim tool with mozjpeg to find the ultimate mix of quality and compression.

Here are some very intelligent answers about the jpegmini compression on Quora: http://www.quora.com/How-does-JPEGmini-r...ny-quality
