Input

Options

The function runs the Harris corner detector on the image. Similarly to cv.cornerMinEigenVal and cv.cornerEigenValsAndVecs, for each pixel (x,y) it calculates a 2 x 2 gradient covariance matrix M(x,y) over a BlockSize x BlockSize neighborhood. Then, it computes the following characteristic:

dst(x,y) = det(M(x,y)) - k * (trace(M(x,y)))^2

Corners in the image can be found as the local maxima of this response map.
