[ITK Community] Regularity term in deformable registration ITK

[Luis Ibanez]

Hi Hana,

When you ask about the "verification of the regularity of the solution",

are you thinking about inspection of the deformation field ?
maybe about visualization of the deformation field ?

or are you thinking about a more formal numerical validation ?

  Thanks

      Luis
