[Insight-users] Input for GeodesicActiveContourLevelsetImageFilter

[Baoyun Li]

Dear All:
 
I want to ask what is the requirement for this filter such as:
 
  geodesicActiveContour->SetInput( IntialLevelSet);
  geodesicActiveContour->SetFeatureImage( speedimage );
 
Now my InitialLevelSet and Speed image have same resolution but with diferent size, when I run the geodesicActiveContour->Update(), the program collaps.
 
I believe the size difference caused the error. I run the geodesicActiveContour at high resultion image before, it works fine.
 
Now my initial level set is obtained from the resample segmentation of lower level, the image size is different with high resolution image due to several times recalucation the image size.
 
Can somebody let me whether the image sizes need to be same.
 
Baoyun
