Image registration is the key process in analyzing images and data from satellites. Feature-based methods find correspondence pixels which point to the same place between two images. In this paper, a wavelet pyramid hierarchical image registration algorithm is presented. First mismatching exclusion policy on the top of pyramid is used. Other hand search strategy which gets the scope of the search layer on the bottom of the pyramid is adopted. Both of them rely on pair of matching-right points. Experimental results show that the algorithm can significantly improve the search efficiency, and obtain a good match accuracy and reliability. |
