Method	Description
Clone ( ) : object	Creates a new object that is a copy of the current instance.
Compute ( IEnumerable points ) : void	Describes all specified points (i.e. computes and sets the orientation and descriptor vector fields of each SpeededUpRobustFeaturePoint.
Compute ( SpeededUpRobustFeaturePoint point ) : void	Describes the specified point (i.e. computes and sets the orientation and descriptor vector fields of the SpeededUpRobustFeaturePoint.
GetDescriptor ( int x, int y, int scale, double orientation ) : double[]	Construct descriptor vector for this interest point
GetOrientation ( SpeededUpRobustFeaturePoint point ) : double	Determine dominant orientation for the feature point.
GetOrientation ( int x, int y, int scale ) : double	Determine dominant orientation for feature point.
SpeededUpRobustFeaturesDescriptor ( IntegralImage integralImage ) : System	Initializes a new instance of the SpeededUpRobustFeaturesDescriptor class.
