Contrast resolution measurement of three primary color of the red, the green and the blue

The color vision contrast resolution is a very important element in human perception and quality assessment for color images. We design a measurement phantom of red, green and blue raster-like to measure the color contrast resolution of three primary color of the red, the green and the blue color based on the digital image processing. The measurement results show that with the variation from 0 to 255 chroma level of the background chroma, the contrast resolution thresholds of human vision that is JND (just noticeable difference) are decreased rapidly at first, and then are increased gradually after the lowest values arrived. we will present the measured results and their mathematical models, It can be expected that such investigations with regard to human vision will establish the physiological foundation of the theories and techniques in hiding bodies and hiding figures, in anti-hiding bodies and anti-hiding figures, in the night vision system independent of infrared, as well as in their relative industries.
