Class BackgroundSubtractorGSOC


  • public class BackgroundSubtractorGSOC
    extends BackgroundSubtractor
    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.

      • apply

        public void apply​(Mat image,
                          Mat fgmask,
                          double learningRate)
        Description copied from class: BackgroundSubtractor
        Computes a foreground mask.
        Overrides:
        apply in class BackgroundSubtractor
        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.

      • getBackgroundImage

        public void getBackgroundImage​(Mat backgroundImage)
        Description copied from class: BackgroundSubtractor
        Computes a background image.
        Overrides:
        getBackgroundImage in class BackgroundSubtractor
        Parameters:
        backgroundImage - The output background image. Note: Sometimes the background image can be very blurry, as it contain the average background statistics.
