Abstract

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.
