Fixing photos

Post by ed »

Back in the day there was a thing called a computer of average transients. what it did, in essence, was overlay repeated events that were time locked. So if you were measuring the evoked response to a light flash, for example, the thing would be triggered to start recording when the flash occurred and would record, say, eeg from surface electrodes. Any one "trace" would be noisy as hell to the point where the response would be obscured. But the ambient eeg is sorta random while the ER is not (with respect to the stimulus). So if you average a number of traces the eeg averages out and you are left with a nice clean waveform, viz:

Well, there is an image version of this. I came across it ages ago when I had an interest in astronomy and astro photography.

Atmospheric distortion is sorta random like the eeg whilst the image (Jupiter and its moos for example) is not. Idea is that you input a bunch of images and it averages them. Neat.

Somebody sent me some crappy images of a luger holster and I thought that this might help clean the images up.

Anyway, here it is
