I need to find out edges in an image in an arbitrary direction. I found sobel or other edge detectors work for horizontal and vertical directions only. Is it possible to extend these to work for any arbitrary direction?
Thanks in advance.

I am not an expert, in image manipulation, but if sobel and other edge detectors work in a direction i don't see why they shouldn't work with a kernel containing a rotated horizontahl or vertical kernels

Have a look at aforge.net
There are loads of different filters and explanations of how they work
