[Insight-users] dense interpolation of sparse vector fields

[Siddharth Srivastava]

Dear ITK users,
           I have some sparsely distributed vectors on a regular grid. Are
there
any methods available in ITK using which I can obtain a dense interpolation
of these vectors over the entire grid?
            Alternatively, are there any published methods which I can
implement using the
filters in ITK to do this?
             It will be fantastic if irregular grids are covered too, but
it is not necessary
for now.
             Thanks a lot for your help,
              Sid.
