  • Abstract
    A new method of measuring image contrast based on local band-limited approach and center-surround retinal receptive field model is devised in this paper. Various evidences from physiological studies corresponding to contrast perception is considered. This method works at multiple scales (frequency bands) and combines the contrast measures obtained at different scales using Lp-norm. Demonstrations of contrast measurement in grayscale and color images using the new method are considered to show its suitability.
