edu.gsu.cs.dmlab.tracking.stages.EdgeWeightCalculatorStageThree

All Implemented Interfaces:

ISTEdgeWeightCalculator

public class EdgeWeightCalculatorStageThree
extends BaseEdgeWeightCalculator

An implementation of the edge weight calculation based upon the third stage in Kempton et. al 2015 and 2018. It utilizes the components of appearance, frame skip, and motion similarity to calculate the edge weight.
