Default Compression "Noise" - 04-23-2008, 12:45 PM

I was working on the attached image this morning and realized it was a good example of the type of the (impressively small) noise you get when running a data compression algorithm on an image. The left photo is the original compressed image - the right is the same data after having been run through a "JPEG Noise Removal" filter in Paint Shop Pro.

(The first couple of YouTube videos posted by Dick Baldwin also show this type of noise.)
