Constructor Detail

BackgroundStationaryGaussian_PL

public BackgroundStationaryGaussian_PL(float learnRate,
                                       float threshold,
                                       boofcv.struct.image.ImageType<boofcv.struct.image.Planar<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 Detail

reset

public void reset()

Description copied from class: BackgroundModel

Resets model to its original state

Specified by:

reset in class BackgroundModel<boofcv.struct.image.Planar<T extends boofcv.struct.image.ImageGray>>

updateBackground

public void updateBackground(boofcv.struct.image.Planar<T> frame)

Description copied from class: BackgroundModelStationary

Updates the background with new image information.

Specified by:

updateBackground in class BackgroundModelStationary<boofcv.struct.image.Planar<T extends boofcv.struct.image.ImageGray>>

segment

public void segment(boofcv.struct.image.Planar<T> frame,
                    boofcv.struct.image.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<boofcv.struct.image.Planar<T extends boofcv.struct.image.ImageGray>>

Parameters:

frame - current image

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