Dubois Anaglyph

Eric Dubois

In 2001, I wrote an ICASSP paper on using least-squares projection in XYZ color coordinates to optimize an analglyph image for a given display and given glasses. This method has been incorporated in a number of software products for producing anaglyphs, often called Dubois Anaglyph (for red-cyan glasses). However, it is equally well applicable to red-cyan, green-magenta and yellow (or amber)-blue glasses. This page collects some information I have on this method. Some stereoscopic images I made can be found on my Flickr site: red-cyan, green-magenta, amber-blue.

Red-Cyan	Amber-Blue (ColorCode 3-D)	Green-Magenta (TrioScopics3D)

Some further examples and many other interesting topics on stereoscopy can be found on the Stereoscopic Gallery of the Art Director's Club of New Jersey (ADCNJ).
