New feature in my program

if (second()%10==0){
　for(int y=0; y<height; y++){
　for(int x=0; x<width; x++){
　if (abs(brightness(motionD[width*y+x])-brightness(get(x,y)))>20){
　counter++;
　}
　motionD[width*y+x]=get(x,y);
　}
　}
　println("Different"+counter);//number of differnt pix
　counter=0;
}

///END

This program check the pixel every 10 second and if the brightnesses are significantly different this program return huge number.

It is possible to apply this program to detect a existence of human in front of static background.
