Constructor Details

BackgroundStationaryGaussian_IL_MT

public BackgroundStationaryGaussian_IL_MT(float learnRate,
 float threshold,
 ImageType<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. Consult a chi-square table for reasonably values. 10 to 16 for 1 to 3 bands.

imageType - Type of input image.

Method Details

reset

public void reset()

Description copied from class: BackgroundModel

Resets model to its original state

Specified by:

reset in class BackgroundModel<T extends ImageInterleaved<T>>

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 ImageInterleaved<T>>

segment

public void segment(T frame,
 GrayU8 segmented)

Description copied from class: BackgroundModelStationary

Invoke to segment input image into background and foreground pixels. If 'segmented' isn't the correct size it will be resized.

Specified by:

segment in class BackgroundModelStationary<T extends ImageInterleaved<T>>

Parameters:

frame - (input) current image

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