[vtkusers] Crest lines extraction

[C. Hiba]

Hi everybody,
I read an image volume consisting of the sequence "headsq" of the vtk library. 
I want to extract the ridge lines (crest lines) of this volume. I know that it must be done with an algorithm called the "marching lines", but I did not find an implementation for this algorithm. 
 The file "vtkLine.h" contains an indication of the marching lines, but not a clear code to extract these lines. 
What shouls i do exactly?


I post with this the image volume and the code i wrote to generate it.

vtkVolume16Reader *Reader = vtkVolume16Reader::New();
Reader->SetDataDimensions(64,64);
Reader->SetFilePrefix("C:/headsq/quarter");
Reader->SetImageRange(1,93);
Reader->SetDataByteOrderToLittleEndian();
Reader->SetDataSpacing(3.2, 3.2, 1.5);


 Thanks for your help
