Well hello guys...

I'm pretty new to Processing but I've been working on how to recognize a face and at the same time place an image on top of it like some webcam softwares out in the market... I'm using Bryan Chung's method to recognize faces (bryanchung.net/?page_id=251) but instead of placing a red rectangle on top of the face I want to place an image thats located on the data folder like sunglasses or something like that. Here's the code:

Code:

import pFaceDetect.*;
import JMyron.*;

PFaceDetect face;
JMyron m;
PImage img;

void setup() {
  size(320,240);
  m = new JMyron();
  m.start(width,height);
  m.findGlobs(0);
  face = new PFaceDetect(this,width,height,
  "haarcascade_frontalface_default.xml");
  frameRate(15);
  // I GUESS THIS IS THE PART THAT HAS TO BE MODIFIED
  img = createImage(width,height,ARGB);
  rectMode(CORNER);
  // HERE'S THE RECTANGLE INSTEAD OF THIS I WANT A IMAGE LOCATED ON THE FOLDER
  noFill();
  stroke(255,0,0);
  smooth();
}

void draw() {
  background(0);
  m.update();
  arraycopy(m.cameraImage(),img.pixels);
  img.updatePixels();
  face.findFaces(img);
  image(img,0,0);
  drawFace();
}

void drawFace() {
  int [][] res = face.getFaces();
  if (res.length>0) {
    for (int i=0;i<res.length;i++) {
      int x = res[i][0];
      int y = res[i][1];
      int w = res[i][2];
      int h = res[i][3];
      rect(x,y,w,h);
    }
  }
}

void stop() {
  m.stop();
  super.stop();
} 

I hope to get answers
Thanks in advance!!!

the rectangle in the original code is:
Code:

rect(x,y,w,h);
 

if you want an image instead of the rectangle you simply need to create a PImage, put your image inside the PImage, draw your image insted of the rectangle; so it should look like:
Code:

...
PImage my_img;
...
void setup(){
...
   my_img = loadImage("yourpath/yourimg.ext");
...
}
void draw(){
...
   image(my_img,x,y); //this is to be placed where in the original there's the rect() call
...
}
 

it's really easy: reading the tutorials and the reference should give you all you need to handle basic processing bits like rect() and image().

maybe next time, when a new problem arises, read the manual before hitting cap lock
