- Abstract:
-
In view of the high computational complexity and the incapability to recognize homogeneous regions of existing circular projection matching algorithms, a new image matching algorithm is proposed in this study. On the basis of hybrid circular projection and combined with pyramid decomposition and angle histogram estimation, the proposed algorithm can not only identify the exact position of the template in the image to be matched but also obtain the rotation angle of the template through the angle estimation strategy. First, candidate points are identified by the image pyramid strategy combined with the hybrid circular projection vector. Then, the positions of the candidate points are precisely located and determined. Finally, the exact angle is calculated by the angle histogram algorithm. The experimental results show the high recognition rate and fast matching speed of the proposed algorithm.
