Parameters

queryDescriptors: Type: Emgu.CVIInputArray
Query set of descriptors.
trainDescriptors: Type: Emgu.CVIInputArray
Train set of descriptors. This set is not added to the train descriptors collection stored in the class object.
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)!
mask (Optional): Type: Emgu.CVIInputArray
Mask specifying permissible matches between an input query and train matrices of descriptors.
stream (Optional): Type: Emgu.CV.CudaStream
CUDA stream.
