Sun Sep 26 10:12:52 EDT 2010

hi,all
I&nbsp;got&nbsp;a&nbsp;problem&nbsp;when&nbsp;I&nbsp;try&nbsp;to&nbsp;use&nbsp;itk::AntiAliasBinaryImageFilter&nbsp;to&nbsp;process&nbsp;the&nbsp;3D&nbsp;image&nbsp;and&nbsp;VtkMarchingCubes&nbsp;to&nbsp;visualise&nbsp;it,&nbsp;
but&nbsp;the&nbsp;output&nbsp;of&nbsp;filter&nbsp;is&nbsp;nothing.I&nbsp;have&nbsp;no&nbsp;idea&nbsp;why&nbsp;the&nbsp;size&nbsp;of&nbsp;output&nbsp;is&nbsp;0,here&nbsp;is&nbsp;part&nbsp;of&nbsp;my&nbsp;code:

typedef&nbsp;float&nbsp;IoPixelType;&nbsp;&nbsp;typedef&nbsp;itk::Image<&nbsp;IoPixelType,&nbsp;3&nbsp;>&nbsp;IoImageType_3D;
typedef&nbsp;itk::AntiAliasBinaryImageFilter<IoImageType_3D,IoImageType_3D>&nbsp;AntiAliasFilterType;
AntiAliasFilterType::Pointer&nbsp;antialias&nbsp;=&nbsp;AntiAliasFilterType::New();
antialias->SetInput(inputimage);
antialias->SetMaximumRMSError(0.01);
antialias->SetNumberOfIterations(50);
antialias->SetNumberOfLayers(&nbsp;2&nbsp;);
DistanceField_s&nbsp;=&nbsp;antialias->GetOutput();

any&nbsp;advice&nbsp;will&nbsp;be&nbsp;appreciated.
