Abstract
We propose a new measure of perceptual image quality basedon a multiple channel human visual system (HVS) model foruse in digital image compression. The model incorporates theHVS light sensitivity, spatial frequency and orientationsensitivity, and masking effects. The model is based on theconcept of local band-limited contrast (LBC) in oriented spatialfrequency bands. This concept leads to a simple maskingfunction. The model has the flexibility to account for thechanges in frequency...Keywords
