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
