Universal Measurement Bounds for Structured Sparse Signal Recovery
Standard compressive sensing results state that to exactly recover an s sparse signal in Rp , one requires O(s · log p) measurements. While this bound is extremely useful in prac...

Supervised model-based visualization of high-dimensional data
When high-dimensional data vectors are visualized on a two- or three-dimensional display, the goal is that two vectors close to each other in the multi-dimensional space should als...

Statistical characterisation of MP3 encoders for steganalysis
This paper outlines a strategy to discriminate different ISO/ MPEG 1 Audio Layer-3 (MP3) encoding programs by statistical particularities of the compressed audio streams. We use ...
