I’m integrating NiftyReg into an extension. (one of the goals is to get the computed transformation/deformation into Slicer) I registered two images with reg\_f3d and saved the control point grid (to later get the deform…

Is there a way to compute the average Hausdorf distances between models so that you can show the average displacement? Also, can you create an average model, or a minimum/maximum model given specified points such as a st…
