Constructor & Destructor Documentation

§ MOG2_GPU()

cv::gpu::MOG2_GPU::MOG2_GPU ( int nmixtures = -1 )

the default constructor

Member Function Documentation

§ getBackgroundImage()

void cv::gpu::MOG2_GPU::getBackgroundImage	(	GpuMat &	backgroundImage,
		Stream &	stream = `Stream::Null()`
	)		const

computes a background image which are the mean of all background gaussians

§ initialize()

void cv::gpu::MOG2_GPU::initialize	(	Size	frameSize,
		int	frameType
	)

re-initiaization method

§ operator()()

void cv::gpu::MOG2_GPU::operator()	(	const GpuMat &	frame,
		GpuMat &	fgmask,
		float	learningRate = `-1.0f`,
		Stream &	stream = `Stream::Null()`
	)

the update operator

§ release()

void cv::gpu::MOG2_GPU::release ( )

releases all inner buffers
