Multi-Scale Probabilistic Dithering for Suppressing Banding Artifacts in Digital Images

Abstract

A method is proposed for reducing the visibility of "banding artifacts," i.e. false contours resulting from color quantization in digital images. The method performs a multi-scale analysis on the neighborhood of each pixel, determines the presence and scale of banding artifacts, and probabilistically dithers (perturbs) the color of the pixel. The overall… (More)
