Member Function Documentation#

getFeatures()#

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 )

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

Parameters

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
