Distance learning and virtual laboratory applications have motivated the use of inexpensive visual stereo solutions for computer displays. The anaglyph method is such a solution. Several techniques have been proposed for the production of anaglyphs. We discuss three approaches: the <i>Photoshop algorithm</i> and its variants, the <i>least squares algorithm</i> proposed by Eric Dubois that optimizes in the CIE color space, and the <i>midpoint algorithm</i> that minimizes the sum of the distances between the anagylph color and the left and right eye colors in CIEL*a*b*. Our results show that each method has its advantages and disadvantages in faithful color representation and in stereo quality as it relates to region merging and ghosting.
