Find homography matrix
WebThe goal of perspective (projective) transform is to estimate homography (a matrix, H) from point correspondences between two images. Since the matrix has a Depth Of Field ( DOF) of eight, you need at least four pairs … WebQuestion: (Homography: 70 points) Compute the homography matrix of the following two images, view \( 1 . p n g \) and view2.png. Find correspondence points (as many as possible to reduce errors) between the two views using corners manually, and improve the locations of the corners by local search with "cornerness" measure.
