Digital watermarking for multimedia information has been widely adopted as a measure to detect for copyrights infringements. In many watermarking schemes, often only one watermarking signature is used in the embedding of hidden information. This paper introduces new multiple sequence families with good autoand cross-correlation properties, which are ideal in the application of digital watermark...

In this paper, we propose a new method of retrieving multi-part, articulate objects from images and video. The scheme is particularly well suited for analyzing images and video for objects that can pose differently with possible shape deformation and articulated motion. The scheme involves computing an invariant signature for each segmented region in the image, in a manner that is insensitive t...
