Syntax

public class FastGlobalSmootherFilter : Algorithm, ICvPtrHolder

Constructors

FastGlobalSmootherFilter(IntPtr)

Creates instance by raw pointer

Declaration

protected FastGlobalSmootherFilter(IntPtr p)

Parameters

Type	Name	Description
IntPtr	p

Methods

Create(InputArray, Double, Double, Double, Int32)

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

Declaration

public static FastGlobalSmootherFilter Create(InputArray guide, double lambda, double sigmaColor, double lambdaAttenuation = 0.25, int numIter = 3)

Parameters

Type	Name	Description
InputArray	guide	image serving as guide for filtering. It should have 8-bit depth and either 1 or 3 channels.
System.Double	lambda	parameter defining the amount of regularization
System.Double	sigmaColor	parameter, that is similar to color space sigma in bilateralFilter.
System.Double	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.
System.Int32	numIter	number of iterations used for filtering, 3 is usually enough.

Returns

Type	Description
FastGlobalSmootherFilter

DisposeManaged()

Filter(InputArray, OutputArray)

Apply smoothing operation to the source image.

Declaration

public virtual void Filter(InputArray src, OutputArray dst)

Parameters

Type	Name	Description
InputArray	src	source image for filtering with unsigned 8-bit or signed 16-bit or floating-point 32-bit depth and up to 4 channels.
OutputArray	dst	destination image.
