title: AdaBoost and Viola Jones: What training set to use?
body: <p>I have implemented my own version of Viola Jones face recognition algorithm that uses AdaBoost as a meta for building a classification committee. My aim is to build a classifier that can recognize whether there is a human face in an image. I am struggling to find adequate set of training data to try out the algorithm. In particular I dont know where to find a set of negative images (i.e. images that do not contain a face). For the positive dataset I was going to try the Labeled Faces in the Wild dataset <a href="http://vis-www.cs.umass.edu/lfw/" rel="nofollow noreferrer">link</a>.</p>
  
  <p>What would be a good negative dataset?</p>
