Assembly:  Emgu.CV.World (in Emgu.CV.World.dll) Version: 4.1.1.3497 (4.1.1.3497)
Syntax
public void MatchAsync(
	IInputArray queryDescriptors,
	IInputArray trainDescriptors,
	IOutputArray matches,
	IInputArray mask = null,
	Stream stream = null
)

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
