Method Details

initialize

public void initialize(int backgroundWidth,
 int backgroundHeight,
 Motion homeToWorld)

Description copied from class: BackgroundModelMoving

Initializes background model. Specifies the size of the background image and transform from the "home" image to the background "world"

Specified by:

initialize in class BackgroundModelMoving<T extends ImageGray<T>,Motion extends InvertibleTransform<Motion>>

Parameters:

backgroundWidth - Width of background

backgroundHeight - Height of background

homeToWorld - Transform from home to world.

reset

public void reset()

Description copied from class: BackgroundModel

Resets model to its original state

Specified by:

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

updateBackground

protected void updateBackground(int x0,
 int y0,
 int x1,
 int y1,
 T frame)

Description copied from class: BackgroundModelMoving

Call to update the background with the frame inside the bounding box. Implementing class needs to make sure the rectangle is inside the background.

Specified by:

updateBackground in class BackgroundModelMoving<T extends ImageGray<T>,Motion extends InvertibleTransform<Motion>>

_segment

protected void _segment(Motion currentToWorld,
 T frame,
 GrayU8 segmented)

Specified by:

_segment in class BackgroundModelMoving<T extends ImageGray<T>,Motion extends InvertibleTransform<Motion>>
