QUALITATIVE ASPECTS OF CHROMO-STEREOSCOPY FOR DEPTH-PERCEPTION

The display of three-dimensional (3D) quantitative data sets is a basi c topic of research in cartography, image processing, and applications related to spatial information. A new application for data visualizat ion and analysis, which combines color vision and depth perception, ha s been developed using the effect known as chromo-stereoscopy based on Einthoven's theory. It enables the generation of flat color composite images from multisource data in which depth information is coded into colors. When viewed with double prism refraction ChromaDepth((TM)) gl asses, a ''dramatic'' 3D effect is produced. Following a description o f the method, the geometric and radiometric processing parameters are qualitatively analyzed to assess their impact on the quality of the ch rome-stereoscopic images and depth perception.
