Detailed Description

Utility for creating a Command that runs FastOpticalFlowOp operator.

Optical flow needs two input images, computes derivatives on them and produces an approximation of motion, ie. the flow.

This utility provides interfacing for those data.

Member Function Documentation

◆ exec()

void exec ( ) const

virtual

Main operation: computes differentials and produces approximation of motion.

Input images: intensity

Differences (output from x, input for the actual algorithm)

Main output (uField,vField, q)

AMVU

AMVV

QIND

Reimplemented from Command.

◆ getDiff()

void getDiff	(	size_t	width,
		size_t	height,
		double	max,
		ImageTray< Channel > &	channels
	)		const

protectedvirtual

Retrieves the difference image needed as a temporary storage. Maybe viewed for debugging.

It is recommended that the image is of type double, as computation of differentials (involving functors) and OpticalFlowWindow use doubles.

Parameters

width	- width of the image
height	- height of the image
max	- expected physical max value (needed if small-integer data used; esp. for subtractions).
channels	- provided resource

Reimplemented in CartesianOpticalFlow.

◆ getGeometry()

virtual const AreaGeometry& getGeometry ( ) const

protectedpure virtual

Main operation: computes differentials and produces approximation of motion.

Desires geometry of the resulting motion field. Implementations may return the resolution of the original data. In derived classes, this could be parameters set by user.

Implemented in CartesianOpticalFlow.
