✦ Synopsis

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 invafiant. Comers are chosen as features and around them an intensity kernel is defined and complex moments are calculated. Then the correspondences are found from similar comers 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. ~'i~ 1997 Pattern Recognition Society. Published by Elsevier Science Ltd.

An important class of radiometric degradations we are faced with often in practice is image blurring. In this paper, special attention is paid to the recognition of the blurred image by complex moment invariant. Some important rules of complex moments for the blurred image are presented and proofed.
