1. A method of embedding data into video, the method comprising:
- receiving video frames including video objects, wherein at least one of the video objects is segmented from the video frames;
embedding data into the at least one video object; and
combining the video objects, including the at least one video object with embedded data, into video frames to produce a video stream including the at least one video object separately embedded with data.

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.

8. A method of embedding a watermark into video, the method comprising;
-
receiving video frames, including at least one video object that has been segmented from the video frames; receiving motion parameters that define motion of the video object in the video frames; embedding a watermark in the video object in plural frames, including using the motion parameters so that location of the watermark in the video frames corresponds to motion of the video object. - View Dependent Claims (9)
