Non-Local Image Dehazing
code: http://www.eng.tau.ac.il/~berman/NonLocalDehazing/
简单明了的图像去雾算法。
首先一幅彩色图像的RGB颜色值可以通过几百个RGB值来表示，类似图像压缩中的调色板。
一幅没有雾的彩色图像近似RGB值在 RGB空间分布为一个 cluster，但是在有雾的彩色图像这些RGB值在RGB空间的对应分布为一条线，我们称之为 haze-lines
一幅图像很多区域可以属于同一条线
4 Haze Removal
Our algorithm is composed of four essential steps：clustering the pixels into haze-lines, estimating an initial transmission map, regularization, and dehazing
结果图示：
