Paper Abstract

Aiming at the influence of geometrical deformation on image matching, the method based on gray-level difference between the nearby pixels detecting multi-pixels edge of image is put forward. To a 256 by 256 image, it needs only 0.14 second to detect edge which is 40% and 35% faster respectively than that of the Prewitt and Robert arithmetic. Applying the method based on multi-pixels edge character to image matching, the influences of edge excursion can be improved obviously: when excursion exists in single pixel point, the relative probability of image matching is improved to 67%; when it exits in edge, it is improved to 50%. Research shows that this method is of simple model, high real-time quality and anti-geometrical-deformation. Most importantly, it is simply conducted.
