[vtkusers] vectorisation of bitmaps

[Benoit Regrain]

Hello,

Is in VTK a process to vectorise an imagedata into one or more polydatas ?
I have in input a bicolor bitmap contained in a vtkImageData object, 
and I would obtain the outlines (in vtkPolyData I think) of the elements 
contained in the vtkImageData.
How could I do that
