Hybrid Image Registration Algorithm of Space Domain and Frequency Domain
空域和频域相结合的景象匹配算法

To resolve the problems existed in unitary algorithm for digital image registration, a hybrid algorithm combining unitized product and phase correlations is put forward. It upgrades the registration probability efficiently. To improve probability and speed of registration more, side constraint competition is used to constraint the edge of image in the paper, and reduction of resolution is taken to decrease calculation scale and increase speed of registration. Simulation shows that the algorithm is successful and practical.
