The Multi-mode Image Registration use Edge Correlation Deviation Combined with Mutual Information

In order to improve the accuracy of multimode image registration, an improved mutual information of medical image registration method is proposed. Firstly, the method calculates the mutual information of the image; then the image edge information is extracted by the edge operator, and the edge correlation deviation of image is calculated. Finally, a new measure function is got by combining the edge correlation deviation with mutual information, and the optimization solution is found by the genetic algorithm. The final result is got by the study of the registration of CT and MRI images, and the registration results are more accurate and stable than the maximum mutual information registration method.
