This paper proposes a new color image segmentation algorithm based on the JND (Just Noticeable Difference) histogram. Histogram of the given color image is computed using JND color model.

Perceptual Watermarking should take full advantage of the results from human visual system (HVS) studies. Just noticeable difference (JND), which refers to the maximum difference that the HVS does not perceive, gives us a way to model the HVS

计算人眼最小失真,结合人眼视觉系统（HVS）的立体感知特性，利用人眼对亮度、纹理、时域和深度辅助信息敏感程度的不同，建立了一个基于深度信息的立体感知JND模型。其中亮度JND模型得到的JND值在3~20之间，纹理JND模型得到的JND值在1~8之间；然后将序列的时域特性和深度信息融合到了空间JND模型中，得到的立体感知JND值在2~20之间，JND值的分布图基本上符合人眼的立体感知特性。-binocular just-noticeable difference
