Abstract

A new image coding approach is proposed by controlling the quantization step via minimizing the perceptual distortions (in terms of image's contrast measurement). The proposed method is a rate-oriented contrast-based approach, which is in contrast to the conventional quality-oriented contrast-based image coding. The algorithm achieves a higher perceptual quality performance against several methods developed previously.
