Abstract:

Distance learning, gaming, and virtual laboratory applications have motivated the use of inexpensive visual stereo solutions for monitor and projection displays. The anaglyph method is such a solution. Several techniques have been proposed for the production of anaglyphs. We discuss the Photoshop algorithm and its variants, and approximation algorithms that depend on the transmission properties of the glasses filters and the spectral decompositions of the display primaries. We consider algorithms using various metrics in the CIE and CIE Lab color spaces. Our results show that each method has its advantages and disadvantages in color representation, computation speed and stereo quality.

Bio:

David McAllister is Professor Emeritus of Computer Science at North Carolina State U. He received his B.S. in Math from UNC-CH, his M.S. in Math from Purdue U., and his Ph.D. in Computer Science from UNC-CH. He joined the faculty at NCSU in 1972. His areas of specialization include electronic music, software reliability, numerical analysis, and computer graphics. He continues to direct graduate students and play jazz piano at local hangouts. He is a VP of an ebook publishing business run by his wife Nancy, and he works out at the gym whenever Nancy can force him to go. He avoids yard work altogether.
