[Insight-users] Moravec interest point detector

[Jian XIE]

Thanks Zachary, If I'm interested in some sort of corner or interesting
point in the image. Like the change is big in all direction. Is there any
other methods? I believe Moravec interest point detector might be more
suitable. I believe the Canny filter can give me some gentle introduction
to ITK. Thanks
