[Insight-users] Sobel Operator Direction

[Andres Munarriz]

Hi fellas!

I'm trying to use the SobelOperator to perform a simple edge detection
but I'm a bit confused by its direction attribute.  What is it, does
it belong in any particular numeric range, is there an optimum value
for it? What does maximally horizontal / vertical translate to (ie. 0
or 1 if so)?


Thank you very much,
