public class BackgroundSubtractorGSOC
extends BackgroundSubtractor

\brief 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.

Method Detail

apply

public void apply(@ByVal
                  Mat image,
                  @ByVal
                  Mat fgmask,
                  double learningRate)

Description copied from class: BackgroundSubtractor

\brief 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.

Description copied from class: BackgroundSubtractor

\brief 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.
