Three methods that improve the visual quality of colour anaglyphs

Anaglyphs are one of the most economical methods for three-dimensional visualization. This method, however, suffers from severe drawbacks such as loss of colour and extreme discomfort for prolonged viewing. We propose several methods for anaglyph enhancement that rely on stereo image registration, defocusing and nonlinear operations on synthesized depth maps. These enhancements substantially reduce unwanted ghosting artefacts, improve the visual quality of the images, and make comfortable viewing of the same sequence possible in three-dimensional as well as the two-dimensional mode of the same sequence.
