Abstract

This paper presents an analysis on how the chrominance subsampling affects the three-dimensional perception in stereoscopic anaglyph videos. The analysis used objectives and subjectives measures of video quality, encoded by color matching red/cyan and green/magenta methods. The chrominance subsampling 4:2:2 and 4:2:0 (at color space YCbCr) was applied for each method of color combination and the results have shown that the method green/magenta is less sensitive than red/cyan method for chrominance subsampling. The analysis also demonstrates that subsampling 4:2:0 is prohibitive for both methods.
