CreateDTFilter(InputArray, double, double, EdgeAwareFiltersList, int)

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

public static DTFilter CreateDTFilter(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
