METHOD OF PROCESSING A DIGITAL IMAGE BY MEANS OF ORDERED DITHERING TECHNIQUE

摘要

An ordered dither method is applied to reduce the chromatic resolution of an image represented by channels R (red), G (green), B (blue) and A (brightness), whereby a first and a second dither matrix is provided, both comprising the same threshold values but arranged in a different spatial distribution. The first dither matrix is applied to the R, B, and A channels, and the second dither matrix is applied to the G channel.
