Feature2D.Compute Method (Mat, KeyPoint[], Mat)

Feature2DCompute Method (Mat, KeyPoint, Mat)

OpenCvSharp Class Library

Compute the descriptors for a set of keypoints in an image.

Namespace: OpenCvSharp.CPlusPlus
Assembly: OpenCvSharp.CPlusPlus (in OpenCvSharp.CPlusPlus.dll) Version: 1.0.0.0 (1.0.0.0)

Syntax

C++

Copy

public virtual void Compute(
	Mat image,
	ref KeyPoint[] keypoints,
	Mat descriptors
)

Public Overridable Sub Compute ( 
	image As Mat,
	ByRef keypoints As KeyPoint(),
	descriptors As Mat
)

public:
virtual void Compute(
	Mat^ image, 
	array<KeyPoint>^% keypoints, 
	Mat^ descriptors
)

abstract Compute : 
        image : Mat * 
        keypoints : KeyPoint[] byref * 
        descriptors : Mat -> unit 
override Compute : 
        image : Mat * 
        keypoints : KeyPoint[] byref * 
        descriptors : Mat -> unit

Parameters

image: Type: OpenCvSharp.CPlusPlusMat
The image.
keypoints: Type: OpenCvSharp.CPlusPlusKeyPoint
The input keypoints. Keypoints for which a descriptor cannot be computed are removed.
descriptors: Type: OpenCvSharp.CPlusPlusMat
Copmputed descriptors. Row i is the descriptor for keypoint i.
