hi people,

i am trying to mask image by using Jmyron. it is working but too slow how can I solve it ? any suggestions?


//////////
import processing.opengl.*;
import JMyron.*;
JMyron m;
PImage[] frames;
PImage img,bg;
float[][] mask;
float decay = 0.016;
//--------------------
void setup(){
 size(320,240,OPENGL);
 m = new JMyron();
 m.start(width,height);
 m.findGlobs(1);
 m.adaptivity(50.0);
 frameRate(50);
 frames = new PImage[2];
 frames[0] = loadImage("car1.jpg");
 frames[1] = loadImage("car2.jpg");
 mask = new float[width][height];
}
//--------------------
void draw(){
 loadPixels();
 m.update();
 m.imageCopy(pixels);
 int[][] b = m.globBoxes();
 for(int i=0 ; i<width ; i++){
   for(int j=0 ; j<height ; j++){
     for(int c=0 ; c<b.length ; c++){
     float brush = brushPower(b[c][0] , b[c][1] ,i,j);
     mask[i][j] = constrain( mask[i][j] - decay + brush, 0 , 1 );
     //pixels[i+j*width] = getPixel(i,j);
    }
   }
   }
updatePixels();
}
//--------------------
float brushPower(int ox, int oy,int x, int y){
 float d = dist(ox,oy,x,y);
 return 0.09*exp(-d*d*0.00025);
}
//--------------------
color getPixel(int i, int j){
 float amount = mask[i][j];
 int index = i+j*width;
 if(amount<0.3333)
   return lerpColor(frames[0].pixels[index],frames[1].pixels[index],3*amount);
 else
   return lerpColor(frames[1].pixels[index],frames[1].pixels[index],2*amount-1);
}

is it now working better?

I might have the same problem,,dont know how to improve the debugging....
