Detailed Description

template<typename T>
class OvFlowT< T >

Class for managing the execution of an optical flow algorithm.

The OvFlowT class manages the execution of an optical flow algorithm, allowing the user to select any image preprocessors, local matching methods, global flow algorithm, and optical flow and occlusion postprocessors.

template<typename T>

bool OvFlowT< T >::doOpticalFlow	(	const OvImageAdapter &	i1,
		const OvImageAdapter &	i2,

		OvImageAdapter &	o1,
		OvImageAdapter &	u2,
		OvImageAdapter &	v2,
		OvImageAdapter &	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.
