Calculating image Gradient

Tue Feb 16, 2010 8:10 am

Hello,

I am making a project in Java. I need to calculate the gradient of an image in both vertical as well as horizontal direction for the same. Is there any function/operator in Java for this?

P.S. : I know about the gradientmagnitude operation that gives the magnitude of gradient. I need to know separate values for gradient in vertical and horizontal direction.
