Abstract:

Inverse Compositional Algorithm is one of the most efficient image alignment algorithms, but the ability of anti-jamming of the algorithm needs to be   improved. The efficiency of the algorithm becomes worse when the image is occluded. We propose an efficient inverse eompositional algorithm with multi-s  cale mask to eliminate disturbance. An adaptive method is used to get the scale of the original mask first, then the mask scale becomes gradually small  to fix on the right place by estimating and bloeking in the iterative process. The experimental results show that our algorithm not only keeps the super  iority of the original inverse composition algorithm, but also enhances the ability of anti-jamming. And the improved inverse composition algorithm can    still be efficient under complex environments.
