I create a sketch with help of OpenCV face detection, in which when a video camera get a face then one image (from the data folder of sketch) has replaced with the face. Also when another face has enter infront of the camera then second image also replace with the second face. And visa versa .. But some time image on faces get changed ..means the image1 on face1 replace on face2 and it continually changed till I close the program..  

I have 4 images in data folder

so I want ..  image1 on face1

                  image2 on face2

                  image3 on face3

                  image4 on face4

                  image1 on face5

                  image2 on face6

                  image3 on face7

                  image4 on face8

I dont know how to solve this problem...??

please help me...
