Constructors

FastGlobalSmootherFilter(nint)

Creates instance by raw pointer

protected FastGlobalSmootherFilter(nint p)

Parameters

p nint

Methods

Create(InputArray, double, double, double, int)

Factory method, create instance of FastGlobalSmootherFilter and execute the initialization routines.

public static FastGlobalSmootherFilter Create(InputArray guide, 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.

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.

Returns

FastGlobalSmootherFilter

DisposeManaged()

Releases managed resources

protected override void DisposeManaged()

Filter(InputArray, OutputArray)

Apply smoothing operation to the source image.

public virtual void Filter(InputArray src, OutputArray dst)

Parameters

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.
