A Fast Scene Matching Algorithm Based on Pixel-Jump Method

According to the image matching demands of both the precision and instantaneity, a real-time two-level scene matching algorithm is proposed based on the least trimmed square Hausdorff distance (LTS-HD). In the first level, a coarse match point is obtained using pixel-jump searching through the reference image. In the second level, a point-by-point local searching is performed to get the accurate match point within the ¿ -neighborhood around the coarse point. Simulation results show that the proposed image matching algorithm takes little time and the point is correct.
