[Insight-users] time between StartRegistration() and first iteration

[Renaud Isabelle]

Hi all,

I am registering 2D or/and 3D images of different modalities data. 

I dont understand why itk registration takes so much time between StartRegistration() and my first iteration in optimizer, first level of multiresolution. 


Any idea how I can reduce time between those 2 steps?

Best regards,
