- W229373452 abstract "ABSTRACTIn this paper, a new methodology for embedding data ina video sequence is presented. In order to obtain the im-perceptibility of the embedded data it is of paramount im-portance to select proper frame regions which guarantee thedata masking. The method we propose to imperceptively in-sert the watermarking, provides suitable spatial embeddinglocations determined by an importance map of the frame.In a given frame, the candidate areas for the embedding, areselected according to the motion rate: a feature which webelieve relevant to human observers. The main idea is toembed the mark in areas characterized by very high or verylow motion rate. The artifacts introduced by the embeddingare less annoying. A subjective experiment has been per-formed to determine the two motion rates.1.
