[Insight-users] input and output images of ZeroCrossingBasedEdgeDetectionImageFilter

[Kai Li]

Hi,
  I tried to use the ZeroCrossingBasedEdgeDetectionImageFilter and my
program won't compile if I set different input and output image types.
The composition of internal filters in its GenerateData() method also
seems to show that same type of input and output image types is necessary.
I think maybe the input and output image types of the Gaussian filter and
the Laplacian filter should all be set to the "TInputImage".

Thanks,

Kai
