篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Classify the pixels into two sets (像素点的分类)相关的知识,希望对你有一定的参考价值。

专题二:基于色度的单幅图像镜面反射分量的分离——像素点的分类


一、像素点分类的标准

回忆一下双色反射模型如下:

$$mathbf{Ileft ( p ight )} = m_{d}left ( p ight )mathbf{I_{d}left ( p ight )}+m_{s}left ( p ight )mathbf{I_{s}}quadquadleft ( 1 ight )$$

目标:对每个像素进行体色分离(body color)。我们对漫反射像素(the pexels with sole diffuse reflection)和高光像素点(the pixels with both specular and diffuse reflections)

①、漫反射像素点

有$mathbf{Ileft ( p-i ight )}=m_{d}left ( p ight )mathbf{I_{d-i}left ( p ight )}$、$I_{MSF-i}left ( p ight )=I_{SF-ileft ( p ight )}+ar{I_{min}}=I_{i}left ( p ight )-I_{min}left ( p ight )+ar{I_{min}}$
