[Insight-users] Perplexed with Optimizer initialization

[Yu Qi]

Hi everybody,
I get to know ITK since only few months ago. I find it is a very well orgnized toolkit for image registration and I made my only application successfully!
 
But there is one thing always confuses me during my programming: 
the selection of parameters :-( . I first copy codes from user guide and it worked. Then I want to change those parameters to see the influence of them to the results. But it not alway turned out a success. 
 
Does anyone can help me with how to configure those parameters, optimizer and metric? What is the most important one which I should take care first? What is the usual range of adjustment? 
 
Or will somebody enclose a paper about optimizers to me?
 
Metric in my application: MattesMutualInformationImageToImageMetric
                                     MutualInformationImageToImageMetric
Optimizer I used: itkVersorRigid3DTransformOptimizer
 
Thank you all!
 
 
 
 
 


Best Regards!
 
Yu Qi
