Video sensor network is evolving from an isolated system to an integral component of the global information infrastructure. In this paper, we argue that when video sensor network ...
Abstract. In this paper, we propose an image moment-based geometric normalization to be applied before embedding and extracting a digital watermark in the DWT-domain of JPEG2000. A...
: We investigate image steganography under re-encoding of images. After a secret message or a digital watermark is embedded into a jpeg image, quite frequently the image is re-enco...
—The pervasive distribution of digital images triggers an emergent need of authenticating degraded images by lossy compression and transmission. This paper proposes a robust cont...
Hidden copyright marks have been proposed as a solution for solving the illegal copying and proof of ownership problems in the context of multimedia objects. Many systems have been...
