Detailed Description

Synthetic frame sequence generator for testing background subtraction algorithms.

It will generate the moving object on top of the background. It will apply some distortion to the background to make the test more complex.

Constructor & Destructor Documentation

cv::bgsegm::SyntheticSequenceGenerator::SyntheticSequenceGenerator	(	InputArray	background,
		InputArray	object,
		double	amplitude,
		double	wavelength,
		double	wavespeed,
		double	objspeed
	)

Python:
	<bgsegm_SyntheticSequenceGenerator object>	=	cv.bgsegm_SyntheticSequenceGenerator(	background, object, amplitude, wavelength, wavespeed, objspeed	)

Parameters

background	Background image for object.
object	Object image which will move slowly over the background.
amplitude	Amplitude of wave distortion applied to background.
wavelength	Length of waves in distortion applied to background.
wavespeed	How fast waves will move.
objspeed	How fast object will fly over background.

void cv::bgsegm::SyntheticSequenceGenerator::getNextFrame	(	OutputArray	frame,
		OutputArray	gtMask
	)

Python:
	frame, gtMask	=	cv.bgsegm_SyntheticSequenceGenerator.getNextFrame(	[, frame[, gtMask]]	)

Obtain the next frame in the sequence.

Parameters

frame	Output frame.
gtMask	Output ground-truth (reference) segmentation mask object/background.
