title: Getting unique faces from image data set. opencv/python
body: <p>I am trying to detect faces from video using opencv haarcascades in python. The face detection works fine for each frame. But if a face is present in multiple frames i'm getting multiple faces of the same person. I now need to get unique faces from my detected faces. Currently I'm trying to us k clustering from opencv on all the data to make clusters and get the unique faces at centers of these clusters. This way I am not getting good results although I get some unique faces.
  Can anyone suggest any other way to only get unique faces from my data?</p>
