Using gaze information to improve image difference metrics

This is the copy of journal's version originally published in Proc. SPIE 6806. Reprinted with permission of SPIE: http://spie.org/x10.xml?WT.svl=tn7We have used image difference metrics to measure the quality of a set of images to know how well they predict perceived image difference. We carried out a psychophysical experiment with 25 observers along with a recording of the observers gaze position. The image difference metrics used were CIELAB _DEab, S-CIELAB, the hue angle algorithm, iCAM and. A frequency map from the eye tracker data was applied as a weighting to the image difference metrics. The results indicate an improvement in correlation between the predicted image difference and the perceived image difference
