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.
