Class EllipsesIntoClusters

java.lang.Object

boofcv.alg.fiducial.calib.circle.EllipsesIntoClusters

public class EllipsesIntoClusters
extends Object

Given an unordered list of ellipses found in the image connect them into clusters. A cluster of ellipses will be composed of ellipses which are spatially close to each other and have major axises which are of similar size.

Constructor Details

EllipsesIntoClusters

public EllipsesIntoClusters(double maxDistanceToMajorAxisRatio,
 double sizeSimilarityTolerance,
 double edgeIntensitySimilarityTolerance)

Configures clustering

Parameters:

maxDistanceToMajorAxisRatio - The maximum distance away the center of another ellipse that will be considered specifies as a multiple of the ellipse's major axis

sizeSimilarityTolerance - How similar two ellipses must be to be connected. 0 to 1.0. 1.0 = perfect match and 0.0 = infinite difference in size

edgeIntensitySimilarityTolerance - How similar the intensity of the ellipses edges need to be. 0 to 1.0. 1.0 = perfect

Method Details

process

public void process(List<BinaryEllipseDetector.EllipseInfo> ellipses,
 List<List<EllipsesIntoClusters.Node>> output)

Processes the ellipses and creates clusters.

Parameters:

ellipses - Set of unordered ellipses

output - Resulting found clusters. Cleared automatically. Returned lists are recycled on next call.
