When "exact recovery" is exact recovery in compressed sensing simulation
In a simulation of compressed sensing (CS), one must test whether the recovered solution x̂ is the true solution x, i.e., “exact recovery.” Most CS simulations employ one of two criteria: 1) the recovered support is the true support; or 2) the normalized squared error is less than . We analyze these exact recovery criteria independent of any recovery algorithm, but with respect to signal distrib...
متن کاملNon-Fourier Motion in The Fourier Spectrum
Typically, image motion analysis in the frequency domain is performed according to the Motion From Fourier Coeecients, or MFFC principle. However , this principle excludes a class of motion that does not generate power spectra containing the origin of the frequency domain, which is usually referred to as Non-Fourier motion. This type of motion includes phenomena relevant to motion analysis such...
متن کاملSPECTRUM OF THE FOURIER-STIELTJES ALGEBRA OF A SEMIGROUP
For a unital foundation topological *-semigroup S whose representations separate points of S, we show that the spectrum of the Fourier-Stieltjes algebra B(S) is a compact semitopological semigroup. We also calculate B(S) for several examples of S.
متن کاملSparse recovery and Fourier sampling
In the last decade a broad literature has arisen studying sparse recovery, the estimation of sparse vectors from low dimensional linear projections. Sparse recovery has a wide variety of applications such as streaming algorithms, image acquisition, and disease testing. A particularly important subclass of sparse recovery is the sparse Fourier transform, which considers the computation of a disc...
متن کاملThe Recovery Spectrum
Recent innovations in alcohol-focused interventions are aimed at closing the gap between population need and the currently uncommon use of alcohol treatment services. Guided by population data showing the heterogeneity of alcohol problems and the occurrence of natural remissions from problem drinking without treatment, alcohol services have begun to expand beyond clinical treatment to offer the...
