Computations are handled with points assumed to lie in index space, not physical space. Reverting to physical space compromises backward compatibility.
Inputs are: (1) A deformable triangular model (Mesh). Import using the SetInput method. (2) A gradient map that make the model deform to fit to the estimated boundary. the gradient should be based on the 2nd derive of the original image. So the nodes on the model surface will stop at the edge features in the original image.
