Class PruneCloseTracks<T>


public class PruneCloseTracks<T> extends Object
Detects if tracks are too close together and discards some of the close ones. Tracks are projected into a smaller grid (specified by scale) and if more than one lands on the same grid element it is pruned. An ambiguity resolver is used to decide which track to keep if there's a conflict. If the resolver says they are equivalent then featureID is used. Results should be consistent independent of order in tracks list. This is designed to work with different types of track data structures.
