[Insight-users] use itkFiniteDifferenceImageFilter

[elhadj meljane]

Hi all,
I try to use  itkFiniteDifferenceImageFilter to iterate with
f_{n+1} = f_n +dt*A_n
and I don't know how to introduce the A_n in this filter, I guess is done in
the filter with ?
FiniteDifferenceImageFilter<..>::GenerateData()
{
...
this->ApplyUpdate()
...
}

is there an itk simple example of an implemntation of the ApplyUpdate() and
how to use it to iterate with this filter.

Thanks,
Elhadj,
