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
