[vtkusers] Number of Points in Marching Cubes

[Andras Lasso]

The result of the registration is a transform that gives you exact correspondence between each point positions between the images, not just a rough initial alignment. Of course you can use a simple rigid transform in the image registration step and then you only get an approximate alignment. But if you only need an approximate alignment you can just as well align using center of gravity, moments, etc.

Thanks Andras!
I hadn't thought about that! 
Now the thing is that I want to build a shape machine learning model, so probably I will need point to point correspondence to build feature vectors.
But I think your idea can be the first step since now the shapes would be are roughly aligned. You think that makes sense?
