IDCT, not FFT, but they're pretty similar in being a spatial to frequency transform. Once the macro blocks are converted, those coefficients can be encoded in quite a few ways by the encoder. ...

junk1, the JPEG image format is very flexable. Most coders already do a sort of perceptual coding phase. For example, blue sky gets compressed very highly because it's just one big solid...

JPEG is coded a a series of macroblocks--8x8 pixels. Then the data from them is coded together with the blocks from the rest of the image. There is room for improvement in both areas.

That's...

Although I would like to encourage improvements and innovation in image storage formats, I have to give this one a jaundiced view. Specifically because I can acheive this level of compresson on...
