Photo enhancement
« on: 03/08/2009 02:51:58 »
Hi, I found this photo yesterday and was hoping someone could enhance it to show what is being reflected better...



Both bits of reflective paper are interesting but I had to giggle when I saw what looks like a person reflected in the reflective paper on the right.

The original HD version is from here:

Its just a reflection of the leg above it, or H G Wells wearing sunglasses.

To me it looks like a Star Trek crew member circa 1990, with a flying saucer behind his head...

I hate to break it to you but image enhancement, of the type shown in films and TV shows, isn't actually possible. You cannot get a higher resolution image than the source image.

Image enhancement in the real world is either what the do to photo's of stars before putting them in the magazines, or taking a corrupted source image and extracting as much of the original as they can. In neither case is the result a higher resolution than the original image.

Any examples of image enhancement that do generate a higher resolution image, through such things as extrapolation of the colour gradients, tends to produce a poor quality, and unreliable, image.

If you can model the specific lens used to take a blurred photo it's possible to sharpen it but you can't do much with a badly pixelated image as there aren't enough datapoints.
