Multiple-Description Speech Coding Using Speech-Polarity Decomposition
We present and evaluate a new multiple-description coding extension to the international standard for pulse code modulation speech coding (ITU-T Rec. G.711). This extension is inse...

Adaptive Run-Length / Golomb-Rice Encoding of Quantized Generalized Gaussian Sources with Unknown Statistics
We present a simple and efficient entropy coder that combines run-length and Golomb-Rice encoders. The encoder automatically switches between the two modes according to simple rul...

Statistical Attack Resilient Data Hiding
In this paper, we propose a discrete cosine transform (DCT) based spread spectrum data-hiding algorithm that is resilient to statistical attacks. Unlike other spread spectrum base...
