FUNCTIONximgproc_createDTFilter

RETURN TYPEximgproc_DTFilter | null

Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

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

guide: guided image (used to build transformed distance, which describes edge structure of guided image).
sigmaSpatial: {\sigma}_H parameter in the original article, it's similar to the sigma in the coordinate space into bilateralFilter.
sigmaColor: {\sigma}_r parameter in the original article, it's similar to the sigma in the color space into bilateralFilter.
mode: one form three modes DTF_NC, DTF_RF and DTF_IC which corresponds to three modes for filtering 2D signals in the article.
numIters: optional number of iterations used for filtering, 3 is quite enough.

Returns

The ximgproc_DTFilter | null result.
