i am using the face detection library's standard example to make a sketch that takes the face of one detected face and puts it in the place of another detected face thereby shifting faces around.

right now i have the standard function of draw faces like this:
Code:

void drawFace() {
  int [][] res = face.getFaces();
  if (res.length>0) {
    for (int i=0;i<res.length;i++) {
	int x = res[i][0];
	int y = res[i][1];
	int w = res[i][2];
	int h = res[i][3];
	rect(x,y,w,h);
    }
  }
} 

and what i think about is to add
Code:

faceImage= get( res[i] [0],res[i] [1],res[i] [2],res[i] [3]); 

with faceImage being PYImage object.

but that would only let me do one picture so i need a way to make an array of PYImages like faceImage [i]

and in the end i would need a function to detect first if there is an even number or uneven.

pseudo code:
if even switch al faces with the face plus 1 and last face = face 0
or something

if uneven the same as above for the biggest even number and the last one gets his face switched with a pre recorded face video.

if you guys can help me anything of the above i say thanks!
kind regards johannes

a small change brings me to the more consistent version:
Code:

void drawFace() {
  int k;
  int [][] res = face.getFaces();
  if (res.length>0) {
    for (int i=0;i<res.length;i++) {
	int x = res[i][0];
	int y = res[i][1];
	int w = res[i][2];
	int h = res[i][3];
	//rect(x,y,w,h);
	//println(i);
	//println((i/2)%2);
	images[i] = get(res[i][0],res[i][1],res[i][2],res[i][3]);
     k=i;
     if(res.length==1){
	 image(images[i],res[i][0],res[i][1],res[i][2],res[i][3]);
	 println("one face");
     }else{
	 k=k-1;
	 if(k>-1){
	  image(images[i],res[i-1][0],res[i-1][1],res[i-1][2],res[i-1][3]);
     }
     }    
    }
  }
}
