DescriptorExtractorCompute Method (IEnumerableMat, KeyPoint, IEnumerableMat)

OpenCvSharp Class Library

Compute the descriptors for a keypoints collection detected in image collection.

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(
	IEnumerable<Mat> images,
	ref KeyPoint[][] keypoints,
	IEnumerable<Mat> descriptors
)

Public Overridable Sub Compute ( 
	images As IEnumerable(Of Mat),
	ByRef keypoints As KeyPoint()(),
	descriptors As IEnumerable(Of Mat)
)

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

abstract Compute : 
        images : IEnumerable<Mat> * 
        keypoints : KeyPoint[][] byref * 
        descriptors : IEnumerable<Mat> -> unit 
override Compute : 
        images : IEnumerable<Mat> * 
        keypoints : KeyPoint[][] byref * 
        descriptors : IEnumerable<Mat> -> unit

Parameters

images: Type: System.Collections.GenericIEnumerableMat
Image collection.
keypoints: Type: OpenCvSharp.CPlusPlusKeyPoint
Input keypoints collection. keypoints[i] is keypoints detected in images[i]. Keypoints for which a descriptor cannot be computed are removed.
descriptors: Type: System.Collections.GenericIEnumerableMat
Descriptor collection. descriptors[i] are descriptors computed for set keypoints[i].
