Abstract
Techniques described herein may determine an objective metric that relates to the color difference that may be perceived by humans viewing two images of the same visual scene. In one implementation, a method may include receiving first and second images; determining a first histogram based on hue values associated with pixels in the first image; and determining a second histogram based on hue values associated with pixels in the second image. A color difference metric may be determined based on a comparison between the first and second histograms. The color difference metric may relate to an objective measure of color differences between the first and second images.
