We present a new scheme for digital watermarking and secure copyright protection of digital images using nonnegative matrix factorization and singular value decomposition approach...
This paper proposes the use of a wireless sensor network of “cat’s eye” augmented with embedded processing, communication, and sensing capabilities to monitor vehicle behavi...
This paper shows an approach for converting bitmap images of text glyphs into a vector format which is suitable for being embedded in XML representations of digitized documents. T...

This paper examines the role of attacker’s memory in Quantization Index Modulation (QIM) watermarking systems. First we derive the attacker’s noise distribution that maximizes...
This paper describes a context information acquisition framework for a personal device that equips a variety of sensors. The framework captures context information about a user an...
