Abstract:
1. A method in a computer system for detecting whether an image contains a face, the method comprising: providing a collection of images, the images having faces at various views: for each of a plurality of views, providing a prior probability that faces in images of the collection will be at that view based on a percentage of the faces in the images of the collection that are at that view; providing detectors for determining whether a window of an image contains a face, each detector adapted to detect faces with a certain view; providing a filter for each detector, the filter for filtering out windows based on a the prior probability associated with the view of the detector; after the prior probabilities have been provided, receiving an image for detecting whether the image contains a face; and for each window of the received image, generating a score relating to a likelihood that the received image contains a face; and for each detector,
