fact.features.muon

Class HoughTransform

java.lang.Object

fact.features.muon.HoughTransform

All Implemented Interfaces:

stream.Processor, stream.StatefulProcessor

public class HoughTransform
extends Object
implements stream.StatefulProcessor

This processor delivers several features that can be used to seperate muon rings from other data using the Hough Transform for circles.
