Claim One:
1. A method of generating person oriented face logs from a video sequence, the method comprising the steps of: acquiring a plurality of frames from the video sequence; detecting a face of an individual within a first frame of the plurality of frames; performing continuous tracking of the face of the individual over the plurality of frames; extracting from the first frame a first face image of the face of the individual; storing the first face image in a face log, the face log for storing face images of the face of the individual; extracting from a second frame of the plurality of frames a second face image of the face of the individual with use of the continuous tracking of the face; determining a first quality score for the first face image, the first quality score based upon assessment of the first face image on the basis of a plurality of criteria; determining a second quality score for the second face image, the second quality score based upon assessment of the second face image on the basis of the plurality of criteria; and performing one of: purging the first face image from the face log and storing the second face image in the face log if the first quality score is below the second quality score and if the second face image is absent from the face log; purging the first face image from the face log if the first quality score is below the second quality score and if the second face image is already stored in the face log; and purging the first face image from the face log if the first quality score is below a minimum quality score.
