Does OpenCV offer a squared norm function for cv::Point?

Question

I have to check several distances between points against a distance threshold. What I can do is taking the square of my threshold and compare it with the squared norm of

Answer 1

It seems there's nothings specific to address this problem.

I thought that one solution could be using the ddot method (dot product), and compute something like

cv::Point distVec = a-b;
double squaredNorm = distVec.ddot(distVec);

If one is willing to take the risk, there's cv::normL2Sqr which requires the input to be in array format: cv::Point might be directly convertible to int[].

I will personally move on by writing my own squared norm.
