Out of the University of Texas comes a new tool that is supposedly able to de-noise images taken with digital cameras. I will try running some of the family photos through at a later date, but first I wanted to see what it wouldn't do. It won't improve blur or rogue compression pixels, and I didn't expect it to. Still, checking that gave me an excuse to play with it. Original:
This was run through the "denoise: high" filter. As you can see, not much difference. (click to enlarge) It can't do anything about the low resolution or the compression fuzziness. Also note, you still can't tell if that's an Uzi magazine or a remote control in Obama's right hand. The smug seems to be present in the same concentration. The stoned also.
