【图像处理】Haar-like特征

 

 特征提取的原理、代码等；

如果是白黑白，是减去一个黑的还是2个黑的，网上有不同的说法；应该需要看原论文了。

 论文原文

The sum of the pixels which lie within the white rectangles are subtracted from the sum of pixels in the grey rectangles. 
A three-rectangle feature computes the sum within two outside rectangles subtracted from the sum in a center rectangle.
