INVARIANCE OF STEREO IMAGES VIA THE THEORY OF COMPLEX MOMENTS

For an approximate epipolar registration of stereo images the transfor mation between the images can be approximated from an affine one to a rotational and translational one. This property can be used to find th e point of correspondences of stereo images in conjunction with comple x moments which are themselves rotational invariant. Corners are chose n as features and around them an intensity kernel is defined and compl ex moments are calculated. Then the correspondences are found from sim ilar corners by finding the L-2 norm of the invariances between the tw o images. From the matched points the respective affine models of the images are also created. (C) 1997 Pattern Recognition Society. Publish ed by Elsevier Science Ltd.
