It seems like it should be possible to make seizure-protecting software or hardware that does what this does in real time - http://trace.umd.edu/peat#download - and filters the screen but I can't seem to find any. Is it infeasible to do this sort of processing in real time? If, say, an HDMI dongle or software could protect epileptics by pre-processing the video signal to remove seizure-inducing content, it would seem like a big win.
