摘要

This paper presents an e.cient template matching which is adapted to both the rotated mono- and multi- sensor images. The proposed method uses the dominant orientation (DO) to estimate the rotation and, use the hill climbing to search the translation. First, to .nd the global optimum, climbers are placed all over the reference image with a constant interval, and each climber is assigned to a unique DO, by which the template rotation can be estimated at each climber. Then a class-adaptive clustering is introduced and all the climbers/DOs are clustered into several classes. In each class the template is rotated only once, so the total rotation operations can be reduced signi.cantly. After the rotation, the hill climbing can be conducted and the global optimum can be achieved by the highest climber. Our method need not any presetting of the parameters, however, it is robust and e.cient, as shown in experiments.
