Matching pursuits video coding using generalized bit-planes
The Matching Pursuits (MP) coding method has been employed successfully in video coding. In it, the motion compensated frame difference is decomposed on an overcomplete dictionary...

Looking at Large Networks: Coding vs. Queueing
— Traditionally, network buffer resources have been used at routers to queue transient packets to prevent packet drops. In contrast, we propose a scheme for large multi-hop netwo...

Perturbed quantization steganography with wet paper codes
In this paper, we introduce a new approach to passive-warden steganography in which the sender embeds the secret message into a certain subset of the cover object without having t...

Rate-Based versus Distortion-Based Optimal Joint Source-Channel Coding
- We consider a joint source-channel coding system that protects an embedded wavelet bitstream against noise using a finite family of channel codes with error detection and error c...
