Averaging images

[cdybedahl]

The other day communicator posted a link to an artist who made images by averaging other images. The result was pretty nifty, so of course I had to try it myself. This is the average of all 78290 frames of Buffy episode 7:22 "Chosen":

They way it should work is that each RGB colour has its own plane in the picture matrix, so that reds get averaged with reds, greens with greens and blues with blues. If I just average two or three images, I get them mixed together but quite visible. It's only when I get into thousands of frames that the green effect appears. And to make it even stranger, when I ran the thing on another episode (7:01 "Lessons") I got a distinctly different shade of green (more yellow, less blue). I think I'll keep experimenting, it makes a nice break from the writing.
