Reprocessing anaglyph images
Henry Gordon Dietz · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2012
In related work, we have shown that conventional digital cameras easily can be modified to directly capture anaglyphs. Anaglyph images commonly have been used to encode stereo image pairs for viewing, but anaglyphs also can be treated as an efficient encoding of two-view image data for reprocessing. Each of the two views encoded within an anaglyph has only partial color information, but our preliminary results demonstrate that the "lost" information can be approximately recovered with any of a variety of reasonably efficient algorithms. This not only allows credible full-color stereo pairs be computationally extracted, but also enables more sophisticated computational photography transformations such as creation of depthmaps and various types of point-spread-function (PSF) substitutions.
