So many people I'd always suspected of evil, and it's all true. posted by devon at 2:03 PM on January 5, 2003
i check sweetcode periodically, and i think that this is far and away my favorite project, and this one is my favorite example from that project.

Ah, Image Analogies. One of the better works to come out of SIGGRAPH 2001. I need to go back and try out the tools again, now that systems are ~3x as fast...they're all open source, conveniently.
I suspect interesting things are possible with image compression -- forget 8x8 blocks, select a chunk and clone the rest.
sweetcode is awesome.. i thought about posting it here before, but figured it wouldn't go over to well..

effugas - isn't that what fractal compression is all about (i'm guessing, as i don't know what the algorithm is behind these things - maybe it's more empirical)?
that image analogy example is amazing. posted by andrew cooke at 2:44 AM on January 6, 2003
Fractal compression seemed to be all about trial and error, if I remember right. Try to find parameters that look like existing output; when you zoom it, it should continue to look like it even smaller.
Yeah, didn't work too great.
IA tries to match shapes and borders in a way that matches the human mind's tendancy to split the visual field into textures and edges. Does a hell of a job, too :-) The link to compression hasn't, I think, been explored too deeply -- certainly, one can imagine the source image as a "dictionary" against which the destination is forged. Reconstruction from a dictionary, even in a lossy manner, is at the heart of many compression algorithms.
