[ITK] [ITK-users] Speed of ITKv4 based Gradient Descent Optimizer

[Jiahui Wang]

Dear All,

I modified ImageRegistration8.cxx to run my own rigid registration.

However, I found that the processing time of ITKv4 based
RegularStepGradientDescentOptimizer is almost 10 times more than that of
ITKv3 based one.

The program was run on the same machine. The only difference is the ITK
libraries.

Could anyone give me some suggestions to solve this issue?

Thanks,

JW
