[Insight-users] GeodesicActiveContours still an unsolved problem

[Ella Maria Kadas]

I still don't really understand what does FastMarchingFilter get as input. I tried the FastMarchingFilter example from ITK/Segmentation and i don't see how providing only the output of the Sigmoid Filter and seed points i only get a black image.I tried to use the SignedDanielssonDistanceFilter and the Image that i get from it looks pretty good. so i used

        smoothing->SetInput([itkImage itkImporter]->GetOutput() );
	gradientMagnitude->SetInput( smoothing->GetOutput() );
	sigmoid->SetInput( gradientMagnitude->GetOutput() );
	
	geodesicActiveContour->SetInput( distanceMap->GetOutput() );
	geodesicActiveContour->SetFeatureImage( sigmoid->GetOutput() );
	
	thresholder->SetInput( geodesicActiveContour->GetOutput() );and update the threshold.But the result is still a black image. Any ideea what am i still doing so wrong.Thanks in advance,   Ella
