Here's a programming question for you experts: can anyone point me to an image processing algorithm that takes an anaglyph as input and reconstructs a full color stereo pair from it?

Reconstructing exactly the original full color stereo pair is impossible, regardless of the anaglpyh method used.

In case of a true or gray anaglyph, a grayscale pair can be reconstructed exactly, for color anaglyph even this is impossible.

In addition the optimal algorithm depends on the anaglyph method use. THere is no standard method for anaglyph creation => no standard method for reverse proces.
Try to load the image in Photoshop and do it manual by color adjutment ....

Assume the standard red-cyan anaglyph for now. I know it's not possible to recover the exact original stereo pair, since some of the information is lost. However, it should be possible to develop an algorithm that comes close. So, I'm not really interested in manual methods. What I want is an algorithm that is able to do this automatically, given that the type of the anaglyph is known beforehand.

I was thinking about applying pattern matching techniques to line up pixel sequences from the left and right images so that their pixel intensities match as closely as possible. Having lined up a pixel sequence, the color information can be completed by copying the missing information from the opposite image.

Anyone done anything like this?

A program called StereoPhoto Maker accepts anaglyph input and separates the left and right picture, which than it can save in any other stereo3d format.
