hi all masters out there,

I have been successful in doing face tracking using openCV. I know there are lot of people who have already achieved it before even I learnt processing, but its a big thing for me to make it working. now the next step for me is to assign an image to the face detected. I have a set of five images, of which I have made an array as following,

   images[0] = loadImage("img1.gif");
   images[1] = loadImage("img2.gif");
   images[2] = loadImage("img3.gif");
   images[3] = loadImage("img4.gif");
   images[4] = loadImage("img5.gif");

I will be assigning the images to faces with as following

 image (images[index],faces[i].x, faces[i].y, faces[i].width, faces[i].height ); 

the above piece of code displays all the images sequentially over the face.

The part which I am not able to do :

I want to assign img.1 to the 1st face detected then randomly assign img. 4 to face 4 detected. now when the face 1  goes out of the camera range the img. 1 assigned to the face should fade out. If the same face(or another face) is detected again then a new image(randomly) should be assigned.


sometimes simple things become very complicated, I know exactly what I want to do but simply not able to put it together so that my machine can understand.

I will be very thankful for your help,
Thanks in advance
