IndexRadiusSearch Method
Performs a radius nearest neighbor search for multiple query points

Namespace:  Emgu.CV.Flann
Assembly:  Emgu.CV.World (in Emgu.CV.World.dll) Version: (
public int RadiusSearch(
	IInputArray queries,
	IOutputArray indices,
	IOutputArray squareDistances,
	double radius,
	int maxResults,
	int checks = 32,
	float eps = 0f,
	bool sorted = true


Type: Emgu.CVIInputArray
The query points, one per row
Type: Emgu.CVIOutputArray
Indices of the nearest neighbors found
Type: Emgu.CVIOutputArray
The square of the Eculidean distance between the neighbours
Type: SystemDouble
The search radius
Type: SystemInt32
The maximum number of results
checks (Optional)
Type: SystemInt32
The number of times the tree(s) in the index should be recursively traversed. A higher value for this parameter would give better search precision, but also take more time. If automatic configuration was used when the index was created, the number of checks required to achieve the specified precision was also computed, in which case this parameter is ignored
eps (Optional)
Type: SystemSingle
The search epsilon
sorted (Optional)
Type: SystemBoolean
If set to true, the search result is sorted

Return Value

Type: Int32
The number of points in the search radius
