Cv.FindFeatures Method (CvFeatureTree, CvMat, CvMat, CvMat, Int32, Int32)

CvFindFeatures Method (CvFeatureTree, CvMat, CvMat, CvMat, Int32, Int32)

OpenCvSharp Class Library

Finds approximate k nearest neighbors of given vectors using best-bin-first search.

Namespace: OpenCvSharp
Assembly: OpenCvSharp (in OpenCvSharp.dll) Version: 1.0.0.0 (1.0.0.0)

Syntax

public static void FindFeatures(
	CvFeatureTree tr,
	CvMat desc,
	CvMat results,
	CvMat dist,
	int k,
	int emax
)

Public Shared Sub FindFeatures ( 
	tr As CvFeatureTree,
	desc As CvMat,
	results As CvMat,
	dist As CvMat,
	k As Integer,
	emax As Integer
)

public:
static void FindFeatures(
	CvFeatureTree^ tr, 
	CvMat^ desc, 
	CvMat^ results, 
	CvMat^ dist, 
	int k, 
	int emax
)

static member FindFeatures : 
        tr : CvFeatureTree * 
        desc : CvMat * 
        results : CvMat * 
        dist : CvMat * 
        k : int * 
        emax : int -> unit

Parameters

tr: Type: OpenCvSharpCvFeatureTree
pointer to kd-tree index of reference vectors.
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.
emax: Type: SystemInt32
The maximum number of leaves to visit.
