Global image smoothing via L0 gradient minimization

dst = cv.l0Smooth(src)
dst = cv.l0Smooth(src, 'OptionName',optionValue, ...)

Input

• src source image for filtering with unsigned 8-bit or signed 16-bit or floating-point depth.

Output

• dst destination image.

Options

• Lambda parameter defining the smooth term weight. default 0.02
• Kappa parameter defining the increasing factor of the weight of the gradient data term. default 2.0
