Caveats on Imaging Formats and Surveillance

Just a few thoughts in my head this morning. One advantage of traditional jpeg over wavelet is that old jpeg can probably be tweaked to use different compression ratios for different areas of the frame. With good foreground/background segmentation, one might chose to compress the background a great deal, while keeping the foreground close to the original.

Again, for video surveillance, keeping the frames totally separated (no reduction of temporal redundancy) is pretty crazy any which way you slice it.
