A Projection Method to Generate Anaglyph Stereo Images by Eric Dubois
Submitted to ICASSP 2001
This web page provides some color images and results for my ICASSP 2001 paper. Results could not be included in the paper, both because of the need for color, and because the proposed method assumes that the resulting anaglyph images are displayed on a CRT and not reproduced on paper.
July 2008: Note that the images shown here were generated for red-blue glasses and do not look very good with the more common red-cyan glasses. Some examples of anaglyph images created with the algorithm of this paper for red-cyan glasses can be found at
To implement equation (4) of the paper, we need the XYZ color-matching functions and the spectral densities of the display phosphors.
The color matching functions are standard, and in addition to the reference  provided in the paper, they can be found online at the website of the Color and Vision Research Laboratories at the University of California San Diego.
The display phosphors for a typical Sony Trinitron CRT are taken from reference . The numerical data was provided by Charles Poynton. See the graph of the these spectral densities.
This section provides some examples of anaglyph images that can be viewed with Red/Blue anaglyph glasses. Anaglyph glasses are available from many sources. The anaglyphs shown here have been optimized for use with the cardboard-frame red/blue glasses (No. 7001) that can be purchased from Reel 3-D Enterprises, Inc. (I have no association with this company).
Example of the method applied to a black and white image
I would like to thank Dr. B. Choquet of CCETT, Rennes, France and the RACE DISTIMA project of the European Community for providing the Piano, Train and Manège stereoscopic images, as well as Kodak for the Basketball image and NHK for the Flower image.
