Method Detail

getPoints

public java.util.ArrayList<java.awt.Point> getPoints()

getArea

public double getArea()

Get percentage fraction of image covered by motion. 0 is no motion on image, and 100 is full image covered by motion.

Returns:

Motion area

getCog

public java.awt.Point getCog()

getWebcam

public Webcam getWebcam()

getPreviousImage

public java.awt.image.BufferedImage getPreviousImage()

Returns last image before the motion. Instance is shared among the listeners, so if you need to change the image, create a copy.

getCurrentImage

public java.awt.image.BufferedImage getCurrentImage()

Returns image with the motion detected. Instance is shared among the listeners, so if you need to change the image, create a copy.

getSource

public WebcamMotionDetector getSource()

Overrides:

getSource in class java.util.EventObject
