Compressed sensing (also known as compressive sensing, compressive sampling, or sparse sampling) is a signal processing technique for efficiently acquiring and reconstructing a signal, by finding solutions to underdetermined linear systems. This is based on the principle that, through optimization, the … Visa mer A common goal of the engineering field of signal processing is to reconstruct a signal from a series of sampling measurements. In general, this task is impossible because there is no way to reconstruct a signal during the times that … Visa mer Compressed sensing relies on $${\displaystyle L^{1}}$$ techniques, which several other scientific fields have used historically. In statistics, the least squares method … Visa mer The field of compressive sensing is related to several topics in signal processing and computational mathematics, such as underdetermined linear-systems Visa mer • "The Fundamentals of Compressive Sensing" Part 1, Part 2 and Part 3: video tutorial by Mark Davenport, Georgia Tech. at SigView, the IEEE Signal Processing Society Tutorial Library. • Using Math to Turn Lo-Res Datasets Into Hi-Res Samples Wired Magazine article Visa mer Underdetermined linear system An underdetermined system of linear equations has more unknowns than equations and generally has an infinite number of solutions. … Visa mer • Noiselet • Sparse approximation • Sparse coding • Low-density parity-check code Visa mer Webbcompressive sensing and information theory.
