Multi-Resolution 3D Image Registration Using Hybrid Powell and Simulated Anneali ng Optimization Algorithm
Shu Huazhong · Journal of Biomedical Engineering Research · 2004
Mutual information (MI)-based global image registratio n has received many attentions these years due to its high accuracy and robustness . MI as criterion to rigidly match 3D CT and MR images are presented. An approac h of multi-resolution sub-sampling is used to speed up the match process, and Po well′s minimization method combined with simulated annealing algorithm is used as optimization strategy. Experimental results show that this method is very eff ective.
