Detailed Description

template<class observation_type>
class state< observation_type >

An abstract class for representing the state of the particle filter.

Member Function Documentation

template<class observation_type>

virtual double state< observation_type >::predict	(	const observation_type &	observation,
		const double	variance_scale = `1.0`
	)			`[pure virtual]`

The importance distribution of the tracker.

Parameters:

`[in]`	observation	The current observation.
`[in]`	variance_scale	A scale factor for the default variance. This is used for annealed filters.

Returns:: The correction factor for the importance distribution (most often 1).
