Simple one-line Fast Global Smoother filter call

dst = cv.FastGlobalSmootherFilter.fastGlobalSmootherFilter(src, guide)
dst = cv.FastGlobalSmootherFilter.fastGlobalSmootherFilter(src, guide, 'OptionName',optionValue, ...)

Input

• src source image for filtering with unsigned 8-bit or signed 16-bit or floating-point 32-bit depth and up to 4 channels.
• guide image serving as guide for filtering. It should have 8-bit depth and either 1 or 3 channels.

Output

• dst destination image.

Options

• Lambda parameter defining the amount of regularization. default 100.0
• SigmaColor parameter, that is similar to color space sigma in cv.bilateralFilter. default 5.0
• LambdaAttenuation internal parameter, defining how much lambda decreases after each iteration. Normally, it should be 0.25. Setting it to 1.0 may lead to streaking artifacts. default 0.25
• NumIter number of iterations used for filtering, 3 is usually enough. default 3

If you have multiple images to filter with the same guide then use FastGlobalSmootherFilter interface to avoid extra computations.
