Applies Paillou filter to an image

dst = cv.GradientPaillou(op, dir)
dst = cv.GradientPaillou(op, dir, 'OptionName',optionValue, ...)

Input

• op Source 8-bit or 16-bit image, 1-channel or 3-channel image.
• dir Gradient direction. One of:
  • X
  • Y

Output

• dst result single image with same number of channel than op.

Options

• Alpha double see paper. default 1.0
• Omega double see paper. default 0.1
