Class AbstractMultiStateTransitionDistribution<T extends Copyable<?>>

java.lang.Object

de.unihalle.informatik.MiToBo.tracking.multitarget.distributions.abstracts.AbstractMultiStateTransitionDistribution<T>

Type Parameters:

T - Type of discrete variables in the multi target state

All Implemented Interfaces:

ConditionalDistribution<AbstractMultiState<T>>, SamplingDistribution<AbstractMultiState<T>>

Direct Known Subclasses:

AbstractMultiStateTransitionDistributionIndep

public abstract class AbstractMultiStateTransitionDistribution<T extends Copyable<?>>
extends Object
implements ConditionalDistribution<AbstractMultiState<T>>, SamplingDistribution<AbstractMultiState<T>>

Abstract class for multi-target state transition distributions. Used in the Bayesian tracking framework. A distribution of this type represents the probability of a multi-target state X_t at time t given a certain multi-target state X_t-1 at time (t-1): p(X_t|X_t-1)
