edge-detection-using-sobel-filter
Here use convulation with sobel filter from scratch in opencv python .
have to detect edge using sobel filter.
- sobel x derivative kernel (detect vertical edge)
-1 0 1
-2 0 2
-1 0 1 - sobel y derivative kernel (detect horizontal edge)
-1 -2 -1
0 0 0
1 2 1
input image
output x derivative
output y derivative
combine of x and y derivative
