Abstract
Chromastereoscopy makes use of special glasses to make its wearer see two slightly different images, one for each eye. With a properly created image this results in perceived depth. It does this by bending light dependent on its wavelength and in the opposite direction for each eye. When a ChromaDepth image is properly created most viewers perceive the image as having a 3D effect. However, since the glasses act on wavelengths and not on perceived colors, different display media like screens and printers could result in a different perception of the images through the glasses. To investigate this possible difference I measured reflectance spectra of printed colors, and created an algorithm to simulate the effect the glasses have on images made with mixes of these colors. Additionally I tried multiple visualization techniques to digitally show the effect including depth.
