OpenCV multiple cascades

Medko

I'm trying to use multiple cascades simultaneously for facial features detection with opencv , atduskgreg's library.

I managed to make it work but because I'm loading the cascades continuously it gets a bit laggy. Can someone show me a better way to achieve this. Thank you.

import gab.opencv.*;
import processing.video.*;
import java.awt.*;

Capture video;

OpenCV opencv;
Detector detector;


PImage pstImage;

void setup() {
  size(640, 480);
  video = new Capture(this, 640, 480);
  opencv = new OpenCV(this, 640, 480);
  detector = new Detector();


  noFill();
  smooth();
  video.start();
}

void draw() {
  opencv.loadImage(video);

  image(video, 0, 0 );
  noFill();
  strokeWeight(1);

  detector.update(OpenCV.CASCADE_FRONTALFACE, 1, 0, 255, 0);
  detector.update(OpenCV.CASCADE_EYE, 2, 255, 0, 0);
  detector.update(OpenCV.CASCADE_NOSE, 3, 0, 0, 255);
  detector.update(OpenCV.CASCADE_MOUTH, 4, 255, 0, 255);
}

void captureEvent(Capture c) {
  c.read();
}


class Detector {

  Detector() {
  }

  void update(String cascade, int column, int R, int G, int B) {
    opencv.loadCascade(cascade);
    Rectangle[] objects = opencv.detect();
    String objName[] = split(cascade, "_");
    String fancyName[] = split(objName[objName.length - 1], ".");

    for ( int i=0; i<objects.length; i++ ) {
      stroke(R, G, B);
      rect( objects[i].x, objects[i].y, objects[i].width, objects[i].height );
      textSize(11);
      text(fancyName[0]+": "+objects[i].width, column*70, (i+1)*10);
    }
  }
}
