A new visual masking tool for JPEG2000

Summary form only given. A nonuniform quantization scheme, based on the perceptual relevance of each channel signal component, has been developed to exploit HVS properties. This strategy is based on the exploitation of the visual masking effect by performing a subband decomposition. An evaluation of the quality was performed using psychophysical measures for validation. The obtained results denote an improvement of the image quality when images are compressed combining intra channel masking visual effect. Furthermore, a compression gain of 10% can be reached depending on the image content.
