Hey Guys,

I have a question, it is possible to remove everything outside the circle so that only my face is visible?

I would be very happy with your help.

Here is my source:

import hypermedia.video.*;
import java.awt.Rectangle;
OpenCV opencv;
//PFont score;
//PImage ballen;
void setup(){
size(600, 450);
//score = loadFont( "ArialMT-16.vlw" );
// ballen = loadImage("bal.png");
opencv = new OpenCV( this );
opencv.capture( width, height ); // open video stream
opencv.cascade( OpenCV.CASCADE_FRONTALFACE_ALT ); // load detection description, here-> front face detection : "haarcascade_frontalface_alt.xml"
ellipseMode(CORNER);
}
public void stop() {
opencv.stop();
super.stop();
}
void draw(){
background(0);
opencv.read();
// proceed detection
Rectangle[] faces = opencv.detect( 1.2, 2, OpenCV.HAAR_DO_CANNY_PRUNING, 40, 40 );
// display the image
// image (opencv.image(), 0, 0);
image (opencv.image(), 0, 0);
// draw face area(s)
noFill();
stroke(255,0,0);
for( int i=0; i<faces.length; i++ ) {
// rect( faces[i].x, faces[i].y, faces[i].width, faces[i].height );
ellipse( faces[i].x, faces[i].y, faces[i].width, faces[i].height);
}
noStroke();
fill(0);
// x, y, breed, hoog
rect(20,10,125,45);
//textFont(score,16);
fill(255);
//text( "Score: " ,25,26);
//text( "Level 1",25,50);
//image(ballen, 19, 75);
//image(ballen, 69, 75);
//image(ballen, 119, 75);
}

Thanks,
