摘要
对颜色视觉感知特性进行了研究,利用HSV空间和Weber-Fechner定律分别讨论了颜色的亮度、色调和饱和度三个分量对主观感知的影响,综合这三方面的影响构造了一种颜色主观信息量函数。将此函数应用于直方图提取,得到一种基于视觉感知特性的颜色直方图。对比试验证明该直方图能稳定提升图像检索性能。
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.
