On Compression of Encrypted Video
We consider video sequences that have been encrypted uncompressed. Since encryption masks the source, traditional data compression algorithms are rendered ineffective. However, it...

Compressive Principal Component Pursuit
We consider the problem of recovering a target matrix that is a superposition of low-rank and sparse components, from a small set of linear measurements. This problem arises in co...

Finding needles in noisy haystacks
The theory of compressed sensing shows that samples in the form of random projections are optimal for recovering sparse signals in high-dimensional spaces (i.e., finding needles ...

Rate-Distortion Optimized Bandwidth Adaptation for Distributed Media Delivery
We propose a framework for rate-distortion optimized bandwidth adaptation via packet dropping at a network node, when the incoming traffic at the node consists of multiple video ...
