Steerable Discrete Cosine Transform
Giulia Fracastoro, Sophie Marie Fosson, Enrico Magli
In image compression, classical block-based separable transforms tend to be inefficient when image blocks contain arbitrarily shaped discontinuities. For this reason, transforms in…
Distributed soft thresholding for sparse signal recovery
Chiara Ravazzi, Sophie M. Fosson, Enrico Magli
In this paper, we address the problem of distributed sparse recovery of signals acquired via compressed measurements in a sensor network. We propose a new class of distributed algo…
Deconvolution of linear systems with quantized input: an information theoretic viewpoint
Fabio Fagnani, Sophie Fosson
In spite of the huge literature on deconvolution problems, very little is done for hybrid contexts where signals are quantized. In this paper we undertake an information theoretic…
