KnnMatch(Mat, Mat, int, Mat?, bool)

Find k best matches for each query descriptor (in increasing order of distances). compactResult is used when mask is not empty. If compactResult is false matches vector will have the same size as queryDescriptors rows. If compactResult is true matches vector will not contain matches for fully masked out query descriptors.

public DMatch[][] KnnMatch(Mat queryDescriptors, Mat trainDescriptors, int k, Mat? mask = null, bool compactResult = false)

Parameters

queryDescriptors Mat

trainDescriptors Mat

k int

mask Mat

compactResult bool

Returns

DMatch[][]

public DMatch[][] KnnMatch(Mat queryDescriptors, int k, Mat[]? masks = null, bool compactResult = false)

Parameters

queryDescriptors Mat

k int

masks Mat[]

compactResult bool
