Detailed Description

template<typename T>
class OvFlowDiffuseMatcherT< T >

Global optical flow algorithm based on fast diffusion (see Ogale et al. ICRA April 05, IJCV July 06).

The OvFlowDiffuseMatcherT implements the fast diffusion based optical flow based on Ogale and Aloimonos, ICRA April 2005 and IJCV July 2006.

template<typename T>

bool OvFlowDiffuseMatcherT< T >::doMatching	(	OvImageT< T > &	i1,
		OvImageT< T > &	i2,
		double	minshiftX,
		double	maxshiftX,
		double	minshiftY,
		double	maxshiftY,

		OvImageT< double > &	u2,
		OvImageT< double > &	v2,
		OvImageT< double > &	o2
	)			[virtual]

Main method for computing optical flow on an image pair. Note: This method modifies the input images, so be careful.

Parameters:

	i1	the first image
	i2	the second image
	minshiftX	method searches for horizontal flow values from minshiftX to maxshiftX
	maxshiftX	method searches for horizontal flow values from minshiftX to maxshiftX
	minshiftY	method searches for vertical flow values from minshiftY to maxshiftY
	maxshiftY	method searches for vertical flow values from minshiftY to maxshiftY
	u1	the horizontal flow for image 1. (method sets this).
	v1	the vertical flow for image 1. (method sets this).
	o1	the occlusion map for image 1. (method sets this).
	u2	the horizontal flow for image 2. (method sets this).
	v2	the vertical flow for image 2. (method sets this).
	o2	the occlusion map for image 2. (method sets this).

Returns:

true if successful.

Implements OvFlowGlobalMatcherT< T >.

template<typename T>

void OvFlowDiffuseMatcherT< T >::setLocalImageMatcher

(

OvLocalMatcherT< T > &

localImageMatcher

)

[virtual]

Specifies the local image matcher to be used by the algorithm.

Parameters:

localImageMatcher

this is an OvLocalMatcherT<T> object which matches a pair of images.

Implements OvFlowGlobalMatcherT< T >.

template<typename T>

bool OvFlowDiffuseMatcherT< T >::setParams	(	int	nparams,
		double *	params
	)			[virtual]

Used for specifying any parameters required.

Parameters:

	nparams	number of parameters which are being passed
	params	the values of the parameters

Returns:

true if successful.

Implements OvFlowGlobalMatcherT< T >.
