ARGUMENTSConstructor or factory

CLASSximgproc_RFFeatureGetter

RETURN TYPEOwned native handle

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

Native object: release it with using or delete(). Factories can return null; check before calling methods. Inherits Algorithm.

Helper class for training part of [P. Dollar and C. L. Zitnick. Structured Forests for Fast Edge Detection, 2013].

Constructors and members

clone

Create another handle to the same native object. This retains the object without copying its pixels or algorithm state; dispose both handles separately.

clone(): this;

Returns

The this result.

getFeatures

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

getFeatures(src: Mat, features: Mat, gnrmRad: number, gsmthRad: number, shrink: number, outNum: number, gradNum: number): void;

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
