Adaptive Exponential Weighted Mutual Information as a Similarity Measure for Medical Image Registration
Bo Hu · Progress in Biomedical Engineering · 2008
In this paper,a new similarity measure for medical image registration,called Adaptive Expo- nential Weighted Mutual Information(AEWMI),is proposed.AEWMI could improve the smoothness and peak keenness performance of similarity measurement curve via adaptively weighting MI according to image quality and resolution.The experimental results,demonstrating the analyzing result,show that our method is robust to image noise or resolution difference and improves the registration robustness effectively.
