Automatic medical image registration based on deviating measurement

An image registration technique based on the gray joint probability of two correlative images is developed and presented. In this paper, a new matching measurement is proposed, i.e. deviating measurement. This parameter quantifies aligning degree of two images, and an image registration scheme based on deviating measurement is developed. Comparing with other similarity measurement(such as normal mutual information), the calculation cost of this registration method is low. Experiment results show that this method is valid and fast.
