A method for detecting undesirable images within an image sequence,
comprising the steps of receiving the image sequence; computing one or
more associated image characteristics for a group of images, wherein the
group of images includes at least one image from the image sequence;
identifying any undesirable group of images based on the computed image
characteristics; collecting undesirable groups of images into at least
one collection; receiving a threshold value of a minimum number of
undesirable images; and flagging images that belong to one or more
collections that have at least the threshold value of undesirable images.
