Invariance of stereo images via the theory of complex moments

Abstract For an approximate epipolar registration of stereo images the transformation between the images can be approximated from an affine one to a rotational and translational one. This property can be used to find the point of correspondences of stereo images in conjunction with complex moments which are themselves rotational invariant. Corners are chosen as features and around them an intensity kernel is defined and complex moments are calculated. Then the correspondences are found from similar corners by finding the L2 norm of the invariances between the two images. From the matched points the respective affine models of the images are also created.
