Histogram of Oriented Gridients(HOG) 方向梯度直方图

Histogram of Oriented Gridients，缩写为HOG，是目前计算机视觉、模式识别领域很常用的一种描述图像局部纹理的特征。这个特征名字起的也很直白，就是说先计算图片某一区域中不同方向上梯度的值，然后进行累积，得到直方图，这个直方图呢，就可以代表这块区域了，也就是作为特征，可以输...

leetcode Largest Rectangle in Histogram 解法二

上一篇文章讲了该题的一个解法。后来又发现一个更好的解法。首先依旧考虑一个升序的数列，例如1,2,3,4,5。那么它的最大矩形显然是有5种可能，即1*5,2*4,3*3,4*2,1*5。所以最大的矩形为9。那么显然不可能是升序的数列。依据以下几条规则对其进行处理。有栈stack和待处理数组a[n]1....
