Hi Bram,

As this is quite specific to your project it might be better to email me about this.

But here is how to draw the image on the biggest face found.
Assuming the ofImage is called img.

If you’re video is 320 240 and you want to draw it at 640 480 - the dimensions of your image will also need to be scaled up.

  
//--------------------------------------------------------------  
void testApp::draw(){  
	ofSetColor(255, 255, 255);  
	cvColor.draw(0, 0, 320, 240);  
	faceFinder.draw(0, 0, 320, 240);  
	  
	ofSetColor(50, 50, 255);  
	ofDrawBitmapString("find those faces!", 10, 15);  
	  
	if(numFaces > 0){  
		ofSetColor(0xFFFFFF);  
		img.draw(faceFinder.blobs[0].boundingRect.x, faceFinder.blobs[0].boundingRect.y, faceFinder.blobs[0].boundingRect.width, faceFinder.blobs[0].boundingRect.height);  
	}	  
	  
}
