I am trying to implement sobel edge detection from scratch but my output can't seem to match with OpenCV's sobel function. I performed correlation on the image with the sobel operator in both x and y directions and then computed gradient magnitude as square root of sum of squares of magnitudes in both x & y direction. I believe the problem is how I assign the threshold for edge detection.

hey, we can help you with opencv usage, but if you need to implement your own (homework ???)

-- this is the wrong place to ask.
