Namespace: Emgu.CV.Features2D
Assembly: Emgu.CV (in Emgu.CV.dll) Version: 2.4.0.1717 (2.4.0.1717)

Syntax

C#
public Matrix<float> ComputeDescriptorsRaw(
	Image<Gray, byte> image,
	Image<Gray, byte> mask,
	VectorOfKeyPoint keyPoints
)
Visual Basic
Public Function ComputeDescriptorsRaw ( _
	image As Image(Of Gray, Byte), _
	mask As Image(Of Gray, Byte), _
	keyPoints As VectorOfKeyPoint _
) As Matrix(Of Single)
Visual C++
public:
virtual Matrix<float>^ ComputeDescriptorsRaw(
	Image<Gray, unsigned char>^ image, 
	Image<Gray, unsigned char>^ mask, 
	VectorOfKeyPoint^ keyPoints
) sealed

Parameters

image
Type: Emgu.CV..::..Image<(Of <(<'Gray, Byte>)>)>
The image where the descriptor will be computed from
mask
Type: Emgu.CV..::..Image<(Of <(<'Gray, Byte>)>)>
The optional mask, can be null if not needed
keyPoints
Type: Emgu.CV.Util..::..VectorOfKeyPoint
The keypoint where the descriptor will be computed from. Keypoints for which a descriptor cannot be computed are removed.

Return Value

The descriptors founded on the keypoint location

Implements

IDescriptorExtractor<(Of <(<'TDescriptor>)>)>..::..ComputeDescriptorsRaw(Image<(Of <<'(Gray, Byte>)>>), Image<(Of <<'(Gray, Byte>)>>), VectorOfKeyPoint)
