Detailed Description

The Base Class for Background/Foreground Segmentation

The class is only used to define the common interface for the whole family of background/foreground segmentation algorithms.

Constructor & Destructor Documentation

§ ~BackgroundSubtractor()

virtual cv::BackgroundSubtractor::~BackgroundSubtractor ( )
virtual

the virtual destructor

Member Function Documentation

§ getBackgroundImage()

virtual void cv::BackgroundSubtractor::getBackgroundImage ( OutputArray  backgroundImage) const
virtual

computes a background image

Reimplemented in cv::BackgroundSubtractorMOG2.

§ operator()()

virtual void cv::BackgroundSubtractor::operator() ( InputArray  image,
OutputArray  fgmask,
double  learningRate = 0 
)
virtual

the update operator that takes the next video frame and returns the current foreground mask as 8-bit binary image.

Reimplemented in cv::BackgroundSubtractorGMG, cv::BackgroundSubtractorMOG2, and cv::BackgroundSubtractorMOG.
