Finds perspective transformation H=||hij|| between the source and the destination planes


- src_points (IntPtr)
- Point coordinates in the original plane, 2xN, Nx2, 3xN or Nx3 array (the latter two are for representation in homogenious coordinates), where N is the number of points.
- dst_points (IntPtr)
- Point coordinates in the destination plane, 2xN, Nx2, 3xN or Nx3 array (the latter two are for representation in homogenious coordinates)
- homography (IntPtr)
- Output 3x3 homography matrix.
