Computing color histogram based on perceptual characteristics
基于视觉感知特性的颜色直方图

The perceptual characteristics of color's Hue, Saturation and Value (HSV) were studied. To measure the information carried by different colors, a function was proposed by virtue of Weber-Fechner law and the hexagonal-pyramid model of HSV color space. It was used later to compute a perception-based color histogram. Contrast experiment proves the effectiveness of the new color histogram in image retrieval.
