两个向量之间的OpenCV欧式距离 [英] OpenCV euclidean distance between two vectors

问题描述

我想计算两个向量(或两个Matrx行，无关紧要)之间的欧几里得距离.在OpenCV中有很好的功能吗?

I want to calculate the euclidean distance between two vectors (or two Matrx rows, doesn't matter). Is there a good function for that in OpenCV?

推荐答案

是.

Mat a,b; // num of rows/cols/channels does not matter, they just have to be equal for both

double dist = norm(a,b,NORM_L2);
