Abstract:
Methods for embedding data, such as digital watermarks, in video objects segmented from video frames. Watermarks are embedded such that they move with the object in the video frames. Interframe motion of video objects is estimated and used to modify the watermark accordingly. Methods for detecting embedded data from video objects are also disclosed.
