Weighted Eigenfunction Estimates with Applications to Compressed Sensing
Using tools from semiclassical analysis, we give weighted L∞ estimates for eigenfunctions of strictly convex surfaces of revolution. These estimates give rise to new sampling techniques and provide improved bounds on the number of samples necessary for recovering sparse eigenfunction expansions on surfaces of revolution. On the sphere, our estimates imply that any function having an s-sparse ex...
متن کاملCompressed sensing – with applications to medical imaging
Compressed sensing is a new approach for acquiring signals. It captures and represents signals and images at a rate significantly below Nyquist rate. In certain areas like magnetic resonance imaging (MRI), it is urgent to reduce the time of the patients’ exposure in the electromagnetic radiation. Compressed sensing breaks the canonical rules and effectively reduces the sampling rate without los...
متن کاملSource - Channel Mappings with Applications to Compressed Sensing
Tandem source-channel coding is proven to be optimal by Shannon given unlimited delay and complexity in the coders. Under low delay and low complexity constraints, joint source-channel coding may achieve better performance. Although digital joint source-channel coding has shown a noticeable gain in terms of reconstructed signal quality, coding delay, and complexity, it suffers from the leveling...
متن کاملCompressed Sensing in Diffusion-Weighted Radial-FSE
Introduction Radial fast spin-echo (Radial-FSE) methods have been used to produce high-resolution diffusion-weighted images that are insensitive to motion and/or magnetic field inhomogeneity [1,2]. However, one of the drawbacks of radial-FSE is the long acquisition time, compared to single shot echo planar imaging, required for high resolution images with sufficient signal to noise ratio (SNR)....
متن کاملCompressed Sensing: Theory and Applications
Compressed sensing is a novel research area, which was introduced in 2006, and since then has already become a key concept in various areas of applied mathematics, computer science, and electrical engineering. It surprisingly predicts that high-dimensional signals, which allow a sparse representation by a suitable basis or, more generally, a frame, can be recovered from what was previously cons...
