DescriptorMatcherRadiusMatchAsync Method (IInputArray, IOutputArray, Single, VectorOfGpuMat, Stream)

http://www.emgu.com
For each query descriptor, finds the training descriptors not farther than the specified distance (asynchronous version).

Namespace:  Emgu.CV.Cuda
Assembly:  Emgu.CV.World (in Emgu.CV.World.dll) Version: 4.1.1.3497 (4.1.1.3497)
Syntax
public void RadiusMatchAsync(
	IInputArray queryDescriptors,
	IOutputArray matches,
	float maxDistance,
	VectorOfGpuMat masks,
	Stream stream
)

Parameters

queryDescriptors
Type: Emgu.CVIInputArray
Query set of descriptors.
matches
Type: Emgu.CVIOutputArray
Matches array stored in GPU memory. Internal representation is not defined.
maxDistance
Type: SystemSingle
Threshold for the distance between matched descriptors. Distance means here metric distance (e.g. Hamming distance), not the distance between coordinates (which is measured in Pixels)!
masks
Type: Emgu.CV.CudaVectorOfGpuMat
Mask specifying permissible matches between an input query and train matrices of descriptors.
stream
Type: Emgu.CV.CudaStream
CUDA stream.
