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.

apply

public void apply(Mat image,
                  Mat fgmask)

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. 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.

finalize

protected void finalize()
                 throws java.lang.Throwable

Overrides:

finalize in class BackgroundSubtractor

Throws:

java.lang.Throwable
