WebbL' acquisition comprimée (en anglais compressed sensing) est une technique permettant de trouver la solution la plus parcimonieuse d'un système linéaire sous-déterminé. Elle englobe non seulement les moyens pour trouver cette solution mais aussi les systèmes linéaires qui sont admissibles. http://www.science4all.org/article/shannons-information-theory/ eacpe12v7a2twb https://annitaglam.com

INTRODUCTION Compressed sensing or compressive sampling (CS) is a theory [1, 2] that merges compression and acquisition, exploiting sparsity to re-cover signals that have been sampled at a drastically lower rate than what the Shannon/Nyquist theorem imposes.

Webb10 apr. 2024 · Compressed sensing theory is the most sensational topic of scientific research in the past century. The original paper was unprecedentedly cited over 30,000 times in only 15 years. WebbCompressed Sensing (CS), also known as compressive sampling, is a DSP technique efficiently acquiring and reconstructing a signal completely from reduced number of measurements, by exploiting its compressibility. The measurements are not point samples but more general linear functions of the signal.
