ofxKinect: getRawDepthPixels same as getRawDepth from Processing ?

Hi all,

I have managed to do a small processing sketch with the Kinect library of Daniel Schiffman for retrieving feet blobs. Now I’m trying to rewrite it in openframeworks but I can’t get it works.

The things that I do not understand is what is the difference in between the Processing ‘getRawDepth()’ (http://www.shiffman.net/p5/kinect/) and the Openframeworks ‘getRawDepthPixels()’ functions ? The Processing function returns an array of int but the Openframeworks one returns what exactly, an array containing arrays of 11bit values ?
If yes how could I transform those 11bits into one int values in order to have the exactly same data as the processing getRawDepth() function ?

If it can helps here is how I do it in processing:

  
  
    
  int feetHeight = 10;  
  int margin = 5;    
  
  ...  
  
  void draw(){  
      ....  
  
     int[] pixels = kinect.getRawDepth();  
  
     for (int i=0; i < kinect.width*kinect.height; i++) {  
  
        if (pixels[i] > floor[i]-margin) {  
          depthImage.pixels[i] = color(0);  
        }   
        else if (pixels[i] < floor[i]-margin-feetHeight) {  
          depthImage.pixels[i] = color(0);  
        }  
        else {  
          depthImage.pixels[i] = color(255);  
        }   
     }  
  
     depthImage.updatePixels();  
  
     ....  
  }  
    
  
  //Calibration-> save the depth values of the floor (with nobody/nothing on it)  
  if (key == ' ') {  
    floor = kinect.getRawDepth();  
  }

Thanks very much for your help!
