Hi,

I'm quite new to processing. I've done a motion tracking object with JMyron library by picking up different exemples...
It's working really nice, but i would like the cross to disapear by becoming smaller...
This is for my last art student project.
I've already done it with Isadora, but it seems that it would be really more efficient with processing.
So if anybody got an idea... I tried to compare previous and current blobCenters lists, but didn't managed, and finally don't think it can work well...
Here is the code of motion detection and tracking
I can send isadora patch if you want to better match what i want to do.


import JMyron.*;
import processing.video.*;
boolean hijack = false;
boolean firstRun = true;

JMyron m;//a camera object

//  Needed on an apple mac?
import quicktime.*;


void setup(){
 size(400,300);

// initialise qt - on a mac only?
try{
           QTSession.open();
}
catch (Exception e) {
           e.printStackTrace();
}

 m = new JMyron();//make a new instance of the object
 m.start(width,height);//start a capture
 m.findGlobs(1);//enable the intelligence
 m.trackColor(255,255,255,3*256-100);

 
 m.update();

 m.adaptivity(12);
 m.adapt();

m.minDensity(250);
m.maxDensity(500);



}

void draw(){
 background(255);


 m.update();//update the camera view
 drawCamera();

 noFill();
 int[][] a;

 //draw center points of globs
 a = m.globCenters();
 stroke(255,255,0);
 for(int i=0;i<a.length;i++){
   int[] p = a[i];
   point(p[0],p[1]);
 }
 
 int [] [] centers = m.globCenters();


 //draw bounding boxes of globs
 a = m.globBoxes();
 rectMode(CORNER);
 fill(0,0,0);
 noStroke();
 rect (0,0,400,300);
 noStroke();
 fill(0,120,220);
 for(int i=0;i<a.length;i++){
   int[] b = a[i];
   rectMode(CENTER);
   rect(b[0], b[1], 6, 35);
   rect(b [0], b [1], 35,6);
 }

 
 //adjust the tracking color
 //using the average color of the current image
 
//  int avgColor = m.average(0,0,width,height);
//  m.trackColor(int(red(avgColor)),int(green(avgColor)),int(blue(avgColor)),150);

}

void drawCamera(){
if(firstRun){
   m.adapt();
   firstRun=false;
}

 //create image of movie
 int[] img = m.differenceImage();
//  int[] img = m.retinaImage();
//  int[] img = m.cameraImage();
 
 //first draw the camera view onto the screen
 loadPixels();
 
}


// Called every time a new frame is available to read

public void stop(){
 m.stop();//stop the object
 super.stop();
}
