摘要:针对传统的DP算法存在条纹瑕疵,提出了一种改进的垂直性约束动态规划立体匹配算法,通过利用扫描线间的相关信息来约束动态规划过程,使得处理每一条扫描线时都能充分利用以前扫描线的匹配信息。实验结果表明,该算法可以明显地消除传统DP算法的视差图的条纹瑕疵,匹配精度高,
而且执行时间短。-ABSTRACT

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
