- W2034146304 abstract "In this paper, we propose and discuss some approaches for measuring perceptual contrast in digital images. Westart from previous algorithms by implementing different local measures of contrast and a parameterized way torecombine local contrast maps and color channels. We propose the idea of recombining the local contrast mapsand the channels using particular measures taken from the image itself as weighting parameters. Exhaustivetests and results are presented and discussed, in particular we compare the performance of each algorithm inrelation to perceived contrast by observers. Current results show an improvement in correlation between contrastmeasures and observers perceived contrast when the variance of the three color channels separately is used asweighting parameter for local contrast maps." @default.
