The introduction of the anaglyph more than a century ago revolutionized the way images could be viewed. For the first time, depth could be perceived on a screen. However, there has been little improvement in the anaglyph since then. Modern threedimensional viewing systems have abandoned the anaglyph for more sophisticated methods, ignoring the cost benefits of anaglyphs. To this day, very little research has been done on anaglyphs and particularly with methods of constructing them. Anaglyphs have traditionally been developed using empirical methods. No scientific approach was available to construct anaglyphs based on measurable properties of the screen and glasses. This led to severe problems with anaglyphs such as the appearance of shadow images or ghosts which give the anaglyph its poor reputation. An approach by Dubois modernized the anaglyph by taking into account spectral properties of the screen and filter to construct a mathematical relationship between the ideal stereoscopic image pair and the anaglyph image. However, his technique also suffered from a phenomenon known as retinal rivalry. This often leads to discomfort and even migraines when viewing anaglyphs even for short periods. This research focuses on tackling the problem of retinal rivalry while simultaneously balancing ghosting and color rendition. To do so, an analysis on the root cause of retinal rivalry is done and integrated into the construction framework originally Yap v developed my Dubois. Additionally, a means for rendering color to deliver smoother gradients is also provided. Using the proposed construction technique, subjective testing was carried out on human observers. Statistical analyses of the results confirm an improvement in retinal rivalry performance of one of the two proposed methods. Interestingly, an improvement in ghosting performance was also observed relative to Dubois technique.
