Hi !
i read that for finding that the homography is good or bad thare are 2 solution:
1.Compute the determinant of the homography, and see if it's too close to zero for comfort. 2.Even better, compute its SVD, and verify that the ratio of the first-to-last singular value is sane (not too high). Either result will tell you whether the matrix is close to singular.
is true this? and there are a method for calculate the svd method in opencv?
thanks
