◆ getFeatures()

virtual void cv::ximgproc::RFFeatureGetter::getFeatures ( const Mat src,
Mat features,
const int  gnrmRad,
const int  gsmthRad,
const int  shrink,
const int  outNum,
const int  gradNum 
) const
pure virtual
cv.ximgproc.RFFeatureGetter.getFeatures(src, features, gnrmRad, gsmthRad, shrink, outNum, gradNum) -> None

This functions extracts feature channels from src. Than StructureEdgeDetection uses this feature space to detect edges.

src: source image to extract features
features: output n-channel floating point feature matrix.
gnrmRad: __rf.options.gradientNormalizationRadius
gsmthRad: __rf.options.gradientSmoothingRadius
shrink: __rf.options.shrinkNumber
outNum: __rf.options.numberOfOutputChannels
gradNum: __rf.options.numberOfGradientOrientations
