FastGlobalSmootherFilter(InputArray, InputArray, OutputArray, double, double, double, int)

Simple one-line Fast Global Smoother filter call. If you have multiple images to filter with the same guide then use FastGlobalSmootherFilter interface to avoid extra computations.

public static void FastGlobalSmootherFilter(InputArray guide, InputArray src, OutputArray dst, double lambda, double sigmaColor, double lambdaAttenuation = 0.25, int numIter = 3)

Parameters

guide InputArray

image serving as guide for filtering. It should have 8-bit depth and either 1 or 3 channels.

src InputArray

source image for filtering with unsigned 8-bit or signed 16-bit or floating-point 32-bit depth and up to 4 channels.

dst OutputArray

destination image.

lambda double

parameter defining the amount of regularization

sigmaColor double

parameter, that is similar to color space sigma in bilateralFilter.

lambdaAttenuation double

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.

numIter int

number of iterations used for filtering, 3 is usually enough.
