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

Syntax

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

Parameters

image
Type: Emgu.CV.GPU..::..GpuImage<(Of <(<'Gray, Byte>)>)>
The image where the descriptor will be computed from
mask
Type: Emgu.CV.GPU..::..GpuImage<(Of <(<'Gray, Byte>)>)>
The optional mask, can be null if not needed
keyPoints
Type: Emgu.CV.GPU..::..GpuMat<(Of <(<'Single>)>)>
The keypoint where the descriptor will be computed from. The order of the keypoints might be changed unless the GPU_SURF detector is UP-RIGHT.

Return Value

The image features founded on the keypoint location
