Monte Carlo non local means: Random sampling for large-scale image filtering
Stanley H. Chan, Todd Zickler, Yue M. Lu
We propose a randomized version of the non-local means (NLM) algorithm for large-scale image filtering. The new algorithm, called Monte Carlo non-local means (MCNLM), speeds up the…

On Sparse Representation in Fourier and Local Bases
Pier Luigi Dragotti, Yue M. Lu
We consider the classical problem of finding the sparse representation of a signal in a pair of bases. When both bases are orthogonal, it is known that the sparse representation is…

Phase Retrieval for Sparse Signals: Uniqueness Conditions
Juri Ranieri, Amina Chebira, Yue M. Lu +1
In a variety of fields, in particular those involving imaging and optics, we often measure signals whose phase is missing or has been irremediably distorted. Phase retrieval attemp…
