ERROR RESILIENT MULTIPLE DESCRIPTION COMPRESSION OF VECTOR GRAPHICS (2008)

Martin Röder, Xiaolin Wu, Sorina Dumitrescu

This research is motivated by the needs of robust streaming of vector graphics contents over the Internet, wireless and other lossy networks. We present a multiple description coding (MDC) technique...

On steganalysis of random lsb embedding in continuous-tone images (2002)

Sorina Dumitrescu, Xiaolin Wu, Nasir Memon

Abstract – In this paper we present an LSB steganalysis technique that can detect the existence of hidden messages that are randomly embedded in the least significant bits of natural...

Pattern Languages versus Parallel Communicating Grammar Systems (1996)

Sorina Dumitrescu, Gheorghe Paun, Arto Salomaa

We compare the power of two (fairly different) recently investigated language identifying devices: patterns and parallel communicating (PC) grammar systems. The simulation of multi-patterns by...
