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
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
