C# Class OpenCvSharp.ORB

Class implementing the ORB (*oriented BRIEF*) keypoint detector and descriptor extractor

described in @cite RRKB11 . The algorithm uses FAST in pyramids to detect stable keypoints, selects the strongest features using FAST or Harris response, finds their orientation using first-order moments and computes the descriptors using BRIEF (where the coordinates of random point pairs (or k-tuples) are rotated according to the measured orientation).

Dispose() protected method

Releases the resources

protected Dispose ( bool disposing ) : void
disposing	bool	/// If disposing equals true, the method has been called directly or indirectly by a user's code. Managed and unmanaged resources can be disposed. /// If false, the method has been called by the runtime from inside the finalizer and you should not reference other objects. Only unmanaged resources can be disposed. ///
return	void

ORB() protected method

protected ORB ( IntPtr p ) : System
p	System.IntPtr
return	System
