Perceptual Color-Difference Thresholds for Images under Different Viewing Conditions

A psychophysical experiment has been conducted to test the threshold of color difference in displayed images under different viewing conditions. Four ISO SCID 400 images N2, N3, N5 and N7 were used as test images, whose colors were altered in lightness, chroma and hue attributes systematically to form the test image pairs with the original ones. The average color difference in all image pairs r...
