We present a mathematical model for network routing based on generating paths in a consistent direction. Our development is based on an algebraic and geometric framework for defini...
: Web Information Systems (WISs) embody a core technology for all larger enterprises. WISs are employed in an intranet or extranet for internal information interchange or communica...
In this paper, we present an original network graph embedding to speed-up distance-range and k-nearest neighbor queries in (weighted) graphs. Our approach implements the paradigm ...
: This paper proposes a new watermarking method for detecting image tampering. First, an authentication number is created using a pair of watermark pixels as the coefficients of a ...
In this paper, we develop a robust image data hiding scheme based on multiple description coding of the signature image. At the transmitter, the signature image is encoded by balan...
