[ITK] [ITK-users] Mattes Mutual Information Speed with 3D Images

Mon Mar 9 19:40:48 EDT 2015

Hello everyone... 

I'm working on a genetic optimizer for Rigid 3D Registration. 

The fitness of each individual is calculated using Mattes Mutual
Information, the execution time of the metric is high ... (30 seconds on
average). This makes the registration too slow. 

Any recommendations? could improve the performance metrics?other most
appropriate metric? 

Regards!
