Detect keypoints in an image and compute the descriptors on the image from the keypoint locations.

Namespace: Emgu.CV.Features2D
Assembly: Emgu.CV.World (in Emgu.CV.World.dll) Version: 4.1.1.3497 (4.1.1.3497)

Syntax

public void DetectAndCompute(
	IInputArray image,
	IInputArray mask,
	VectorOfKeyPoint keyPoints,
	IOutputArray descriptors,
	bool useProvidedKeyPoints
)

Public Sub DetectAndCompute ( 
	image As IInputArray,
	mask As IInputArray,
	keyPoints As VectorOfKeyPoint,
	descriptors As IOutputArray,
	useProvidedKeyPoints As Boolean
)

public:
void DetectAndCompute(
	IInputArray^ image, 
	IInputArray^ mask, 
	VectorOfKeyPoint^ keyPoints, 
	IOutputArray^ descriptors, 
	bool useProvidedKeyPoints
)

member DetectAndCompute : 
        image : IInputArray * 
        mask : IInputArray * 
        keyPoints : VectorOfKeyPoint * 
        descriptors : IOutputArray * 
        useProvidedKeyPoints : bool -> unit

Parameters

image: Type: Emgu.CVIInputArray
The image
mask: Type: Emgu.CVIInputArray
The optional mask, can be null if not needed
keyPoints: Type: Emgu.CV.UtilVectorOfKeyPoint
The detected keypoints will be stored in this vector
descriptors: Type: Emgu.CVIOutputArray
The descriptors from the keypoints
useProvidedKeyPoints: Type: SystemBoolean
If true, the method will skip the detection phase and will compute descriptors for the provided keypoints
