Method Detail

getBackground

public boofcv.struct.image.Planar<boofcv.struct.image.GrayF32> getBackground()

Returns the background image. Pixels which haven't been assigned yet are marked with Float.MAX_VALUE.

Returns:

background image.

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<boofcv.struct.image.Planar<T extends boofcv.struct.image.ImageGray>,Motion extends georegression.struct.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<boofcv.struct.image.Planar<T extends boofcv.struct.image.ImageGray>>

updateBackground

protected void updateBackground(int x0,
                                int y0,
                                int x1,
                                int y1,
                                boofcv.struct.image.Planar<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<boofcv.struct.image.Planar<T extends boofcv.struct.image.ImageGray>,Motion extends georegression.struct.InvertibleTransform<Motion>>

_segment
