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

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

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

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

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

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

one form three modes DTF_NC, DTF_RF and DTF_IC which corresponds to three modes for filtering 2D signals in the article.
System.Int32 numIters

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

Filter(InputArray, OutputArray, Int32)

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.

Declaration
public virtual void Filter(InputArray src, OutputArray dst, int dDepth = -1)
Parameters
Type Name Description
InputArray src
OutputArray dst
System.Int32 dDepth
