If I have 4 point correspondences, eg: (x1,y1), (x2,y2), (x3,y3), (x4,y4), and I want to compute the H matrix.
I create the A matrix using the 4 points and have a 8*9 matrix.
I calculate SVD using [U, D, V] = svd(A).
Do I use U or V as the eigen vectors of the smallest eigen value to create H. How to create H matrix here?
