Detailed Description

Implementation of the different yet better algorithm which is called GSOC, as it was implemented during GSOC and was not originated from any paper.

This algorithm demonstrates better performance on CDNET 2014 dataset compared to other algorithms in OpenCV.

Member Function Documentation

virtual void cv::bgsegm::BackgroundSubtractorGSOC::apply ( InputArray  image, OutputArray  fgmask, double  learningRate = -1  )

pure virtual

Python:
	fgmask	=	cv.bgsegm_BackgroundSubtractorGSOC.apply(	image[, fgmask[, learningRate]]	)

Computes a foreground mask.

Parameters

image	Next video frame.
fgmask	The output foreground mask as an 8-bit binary image.
learningRate	The value between 0 and 1 that indicates how fast the background model is learnt. Negative parameter value makes the algorithm to use some automatically chosen learning rate. 0 means that the background model is not updated at all, 1 means that the background model is completely reinitialized from the last frame.

Implements cv::BackgroundSubtractor.

virtual void cv::bgsegm::BackgroundSubtractorGSOC::getBackgroundImage ( OutputArray  backgroundImage ) const

pure virtual

Python:
	backgroundImage	=	cv.bgsegm_BackgroundSubtractorGSOC.getBackgroundImage(	[, backgroundImage]	)

Computes a background image.

Parameters

backgroundImage

The output background image.

Note

Sometimes the background image can be very blurry, as it contain the average background statistics.

Implements cv::BackgroundSubtractor.
