Class GestureModel

java.lang.Object
  org.wiigee.logic.GestureModel

public class GestureModel
extends java.lang.Object

This Class units a Quantizer-Component and an Model-Component. In this implementation a k-mean-algorithm for quantization and a hidden markov model as instance for the model has been used.

Constructor Summary

GestureModel()
Creates a Unit (Quantizer&Model).

Method Summary

double	getDefaultProbability() Returns the model probability for bayes.
HMM	getHMM()
int	getNumObservations()
int	getNumStates()
Quantizer	getQuantizer()
double	matches(Gesture gesture) Returns the probability that a gesture matches to this gesture model.
void	print() For debug purposes or very technical interested people. :)
void	printMap() For debug purposes or very technical interested people. :)
void	setDefaultProbability(double prob)
void	setHMM(HMM hmm)
void	setQuantizer(Quantizer q)
void	train(java.util.Vector<Gesture> trainsequence) Trains the model to a set of motion-sequences, representing different evaluations of a gesture
