Figure 8From: A framework for measuring sharpness in natural images captured by digital cameras based on reference image and local areasThe average LCC of the proposed metric and the subjective sharpness. (a) LCC values for Datasets I and II as a function of the number of blocks, m, with M = 50, 75, 100, and 125. (b) The average LCC of the proposed metric as a function of the block number, i, when M = 100.Back to article page
