for image diffs, there's https://github.com/HumbleSoftware/js-imagediff/ but by the looks of https://github.com/HumbleSoftware/js-imagediff/blob/master/js/imagediff.js#L166, it doesn't use typed arrays and compares at the sub-pixel level. i would be tempted to rewrite it for a considerable speed boost.
That's really cool. It might also be possible to port or gificles optimizer to js, or compile it with emscripten
feel free to draw inspiration from my fresh-from-the-oven implementation based on the omggif encoder

cheers!
EDIT my lib still places full-size frames (w/ transparency fill), I'll add logic in a couple days to return cropped frames w/offsets from the diff algo...
Hi leeoniya , you did the great tool, is there any solution for this issue?tks
+1 Image file sizes are really large with gif.js by default
if you look at http://i.imgur.com/wypWt11.gif in GIMP you'll see why it fits into 3.95k, each frame is a delta from the previous frame.
i did a screen record with lossless codec at 60fps, compressed with gifsicle, which computed the background, frame deltas and i think also removed identical frames (which may be fast to identify with a hash or similar) or maybe it merged identical frames into longer-delayed single frames.
the original image size was tiny, each square block is a pixel. so if #2 is addressed, this would probably scale & encode in a < 100ms.
