You might want to take a look at this post:

constraining parameters during optimization

For example, I’m using the Similarity2DTransform. Here, I would like to enforce that the scale must be non-zero and positive, however I would like to allow for negative translation. Is it correct, that the only optimizer which can handle constraints is the LBFGSBOptimizer? But, it looks like that I can only constraint all parameters with the same bounds - is this correct? So I tried something like this: R = sitk.ImageRegistrationMethod() R.SetInitialTransform(sitk.Similarity2DTransform()) R.…
