Constructors

DTFilter(nint)

Creates instance by raw pointer

protected DTFilter(nint p)

Parameters

p nint

Methods

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

Factory method, create instance of DTFilter and produce initialization routines.

public static DTFilter Create(InputArray guide, double sigmaSpatial, double sigmaColor, EdgeAwareFiltersList mode = EdgeAwareFiltersList.DTF_NC, int numIters = 3)

Parameters

guide InputArray

guided image (used to build transformed distance, which describes edge structure of guided image).

sigmaSpatial double

sigma_H parameter in the original article, it's similar to the sigma in the coordinate space into bilateralFilter.

sigmaColor double

sigma_r parameter in the original article, it's similar to the sigma in the color space into bilateralFilter.

mode EdgeAwareFiltersList

one form three modes DTF_NC, DTF_RF and DTF_IC which corresponds to three modes for filtering 2D signals in the article.

numIters int

optional number of iterations used for filtering, 3 is quite enough.

Returns

DTFilter

DisposeManaged()

Releases managed resources

protected override void DisposeManaged()

Filter(InputArray, OutputArray, int)

Simple one-line Domain Transform filter call. If you have multiple images to filter with the same guided image then use DTFilter interface to avoid extra computations on initialization stage.

public virtual void Filter(InputArray src, OutputArray dst, int dDepth = -1)

Parameters

src InputArray

dst OutputArray

dDepth int
