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

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.
