[Insight-users] itk2DEdgeDetectionSample (fwd)

[Xinwei Xue]

Hi Josh,

Thanks for the reminder, I actually was not on the users list. I should
have added myself to the list.

It's ture the itk2DEdgeDetection.txx should be renamed to .cxx file.
I also looked at the code for zerocrossing based edge detection and canny
edges and seems fine. but the result is not good. I'll do a careful
check tomorrow and let you guys know what's the problem asap. 
Sorry for the inconvenience.


Thanks,

Xinwei
