    opencv.capture( 160, 120 );
}

void draw() {

    opencv.read();                               // grab frame from camera
    image( opencv.image(), 0, 0);                // show the original image

    opencv.absDiff();                            // make the difference between the current image and the image in memory

    image( opencv.image(OpenCV.MEMORY), 160, 0 );  // display the image in memory on the right
    image( opencv.image(), 160, 120 );             // display the result on the bottom right
}

void keyPressed() {
    
    opencv.remember();  // store the actual image in memory
}
