Hi,

        I have a question about the CannyEdgeDetectionImageFilter =
behavior.

In fact, I've tested it on a simple cube image (255 is inside and 0 =
outside).=20
The result is quite surprising : in place a having one plan by side of =
the cube,
I have three plans.

If someone knows the reason, please tell me.

    Thanks in advance.

    Julien, BELGIUM
