Constructor & Destructor Documentation

BGCalibration::BGCalibration	(	const math::Vector2< unsigned int > &	pFrameSize,
		unsigned int	pChannelCount,
		unsigned int	pCalibFrameCount,
		bool	pContCalibration
	)

create background calibration

Parameters:

	pFrameSize	frame size
	pChannelCount	channel count
	pCalibFrameCount	number of frames to calibrate background
	pContCalibration	calibration mode: true: continuous calibration, flag: initial calibration

BGCalibration::BGCalibration	(	const math::Vector2< unsigned int > &	pFrameSize,
		unsigned int	pChannelCount,
		unsigned int	pCalibFrameCount,
		const base::String &	pCalibFileName
	)

create background calibration

Parameters:

	pFrameSize	frame size
	pChannelCount	channel count
	pCalibFrameCount	number of frames to calibrate background
	pContCalibration	calibration mode: true: continuous calibration, flag: initial calibration
	pCalibFileName	file to write calibration data to or to read calibration data from

if pCalibFileName exists, read calibration data from file whenever calibration is performed again, write the new calibration data into file
