Syntax

public void FindFeatures(
	CvMat desc,
	CvMat results,
	CvMat dist,
	int k
)

Public Sub FindFeatures ( 
	desc As CvMat,
	results As CvMat,
	dist As CvMat,
	k As Integer
)

public:
void FindFeatures(
	CvMat^ desc, 
	CvMat^ results, 
	CvMat^ dist, 
	int k
)

member FindFeatures : 
        desc : CvMat * 
        results : CvMat * 
        dist : CvMat * 
        k : int -> unit

desc: Type: OpenCvSharpCvMat
m x d matrix of (row-)vectors to find the nearest neighbors of.
results: Type: OpenCvSharpCvMat
m x k set of row indices of matching vectors (referring to matrix passed to cvCreateFeatureTree). Contains -1 in some columns if fewer than k neighbors found.
dist: Type: OpenCvSharpCvMat
m x k matrix of distances to k nearest neighbors.
k: Type: SystemInt32
The number of neighbors to find.
