For running motion detect on a network camera that is delivering
individual JPEGs, I'm thinking of comparing/subtracting two jpegs -
with imagemagick, "composite img1 img2 -compose difference
difference.jpeg" works quite well. To do it programmatically however,
I seem to have a number of options -
libgd has a nice an easy interface, but is a little primitive for this.
The imagecompare function isn't sufficiently flexible, and occasionally
imagemagickcore seems to be a big gun, but looks okay. I can't find a
way to read in an image already in memory though, only from file.
I don't now libjpeg at all, but that's where I'm going next.
Any other I might want to consider?
