[Insight-users] itkVectorConfidenceConnectedImageFilter does not pass concept checking

[sebastian ordas]

Hello David,

sorry for not having looked into the tests before asking  in the mailing 
list

My PixelType could be unsigned char, short, unsigned short, etc; but not 
itk::RGBPixel ...

this explains why the concept check did not pass

I will submit an example if I finally use this filter

thank you
sebastian
