hello everybody,
i´m new to processing, i´ve done a few things but there is still alot i often don´t understand or get to work.

i wonder if or how it is possible to have two objects in a sketch which will blur in a different way by using opencv.

first if tried this:

1. import hypermedia.video.*;
   OpenCV opencv,opencv2;
   
   void setup(){
   size( 1200, 1600 );
    opencv = new OpenCV(this);
    opencv2 = new OpenCV(this);
   
   }
   void draw(){
   float myVar = mouseY;
   myVar= map(myVar,0,1200,0,60);
    
   opencv.loadImage("mein_zimmer1_nachvorn_00.png");
   opencv.blur( OpenCV.BLUR, 50);
   image( opencv.image(), 0, 0 );
   
   opencv2.loadImage("mein_zimmer1_NURvorn_00.png");
   opencv2.blur( OpenCV.BLUR, int(myVar));
   image( opencv2.image(), 0, 0 );
   }
   

...and later i found the allocate statement and tried the following, but i don´t get it to work.
it always just uses the lowest blur value.

1. import hypermedia.video.*;
   OpenCV opencv,opencv2;
   
   void setup(){
   size( 1200, 1600 );
    opencv = new OpenCV(this);
    opencv.allocate(width,height); 
    opencv2 = new OpenCV(this);
    opencv2.allocate(width,height);
   }
   
   void draw(){
   float myVar = mouseY;
   myVar= map(myVar,0,1200,0,60);
   
   opencv.loadImage("mein_zimmer1_background_00.png");
   opencv.copy("mein_zimmer1_background_00.png");
   opencv.ROI( 550, 300, 200, 500 );
   opencv.blur( OpenCV.BLUR, int(myVar) );
   image( opencv.image(), 0, 0 );
   
   opencv2.loadImage("mein_zimmer1_background_00.png");
   opencv2.copy("mein_zimmer1_background_00.png");
   opencv2.ROI( 250, 300, 200, 200 );
   opencv2.blur( OpenCV.BLUR, mouseY );
   image( opencv2.image(), 0, 0 );
   }

can you explain me how to use the allocate statement right or maybe another way to have multiple images in a sketch that all blur in a diffent value.

thanks alot, stefan
