Distributed Coding of Shifts using the DFT Phase
In this paper we consider the problem of image encoding with side information at the decoder, where the side information is an integer shifted version of the image at the encoder....

Resolution Limits of Sparse Coding in High Dimensions
This paper addresses the problem of sparsity pattern detection for unknown ksparse n-dimensional signals observed through m noisy, random linear measurements. Sparsity pattern rec...

Component-based image coding using non-local means filtering and an autoregressive texture model
While noise is usually regarded as a problem of the image formation process, we observe that it is also frequently part of natural texture. In this paper, we present a concept for...

Efficient code diversification for network reprogramming in sensor networks
As sensors in a network are mostly homogeneous in software and hardware, a captured sensor can easily expose its code and data to attackers and further threaten the whole network....

Joint source-channel rate control for pixel-domain distributed video coding
We study the scenario of pixel-domain distributed video coding for noisy transmission environments and propose a method to allocate the available rate between source coding and ch...
