Instructions:

Point the camera at a white background and make a dark silhouette with your hand. you should see your hand converted to a vector-based shape and rerendered in green outline.

import JMyron.*;

JMyron m;   //a camera object

void setup(){
   size(320,240);
   m = new JMyron();        //make a new instance of the object
   m.start(width,height);   //start a capture at 320x240
   m.minDensity(100);       //minimum density - you'll need to tweak this, probably.
   m.trackColor(0,0,0,150); //color to track, and tolerance.  need to tweak this as well.

   println("Myron " + m.version());
   noFill();
}

void draw(){

   // GET THE IMAGE PIXELS

   m.update();                             //update the camera view
   int[] img = m.image();                  //get the normal image of the camera

   loadPixels();                           //load the pixels[] array

   for(int i=0 ; i < width*height ; i++)   //loop through all the img pixels
      pixels[i] = img[i];                  //   copy to pixel to be displayed

   updatePixels();                         // show pixels[] on the screen

   // DRAW THE OUTLINES

   stroke(0,150,0);                        // set stroke color

   int[][][] list = m.globEdgePoints(30);  //get the outlines

      beginShape(LINE_LOOP);
      if(list[i]!=null)
         for(int j=0 ; j < list[i].length ; j++)
            vertex(list[i][j][0],list[i][j][1]);
      endShape();
   }

}

public void stop(){
