Constructor Detail

BackgroundStationaryGaussian_SB

public BackgroundStationaryGaussian_SB(float learnRate,
                                       float threshold,
                                       java.lang.Class<T> imageType)

Configurations background removal.

Parameters:

learnRate - Specifies how quickly the background is updated. 0 = static 1.0 = instant. Try 0.05

threshold - Threshold for background. Try 10.

imageType - Type of input image.

Method Detail

reset

public void reset()

Description copied from class: BackgroundModel

Specified by:

reset in class BackgroundModel<T extends ImageGray>

updateBackground

public void updateBackground(T frame)

Description copied from class: BackgroundModelStationary

Updates the background with new image information.

Specified by:

updateBackground in class BackgroundModelStationary<T extends ImageGray>

segment

public void segment(T frame,
                    GrayU8 segmented)

Description copied from class: BackgroundModelStationary

Invoke to use the background image to segment the current frame into background and foreground pixels

Specified by:

segment in class BackgroundModelStationary<T extends ImageGray>

Parameters:

frame - current image

segmented - Segmented image. 0 = background, 1 = foreground/moving
