Compressed sensing for electrocardiogram acquisition in wireless body sensor network: A comparative analysis

open access: yesInternational Journal of Distributed Sensor Networks, 2019
In the past decades, compressed sensing emerges as a promising technique for signal acquisition in low-cost sensor networks. For prolonging the monitoring duration of biosignals, compressed sensing is also exploited for simultaneous sampling and ...

Segmented Multistage Reconstruction of Magnetic Resonance Images

open access: yesAdvances in Electrical and Computer Engineering, 2021
Compressed sensing of magnetic resonance imaging refers to the reconstruction of magnetic resonance images from partially sampled k-space data. The k-space data reduces reconstruction processing time but at the cost of increasing artifacts - especially

Compressed Sensing with nonlinear observations and related non-linear optimisation problems

open access: yes, 2013
Non-convex constraints have recently proven a valuable tool in many optimisation problems. In particular sparsity constraints have had a significant impact on sampling theory, where they are used in Compressed Sensing and allow structured signals to be ...

Sequential Compressed Sensing [PDF]

open access: yesIEEE Journal of Selected Topics in Signal Processing, 2010
Compressed sensing allows perfect recovery of sparse signals (or signals sparse in some basis) using only a small number of random measurements. Existing results in compressed sensing literature have focused on characterizing the achievable performance by bounding the number of samples required for a given level of signal sparsity. However, using these

Acute Neurological Events in Children With Hemoglobin SC Disease: A Multicenter Retrospective Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Neurological manifestations in children with hemoglobin SC (HbSC) disease remain insufficiently characterized, particularly regarding acute events. The aim of this study was to describe the spectrum and frequency of acute neurological events in a multicenter cohort of children with HbSC disease.

Compressed hyperspectral sensing [PDF]

open access: yesSPIE Proceedings, 2015
Acquisition of high dimensional Hyperspectral Imaging (HSI) data using limited dimensionality imaging sensors has led to restricted capabilities designs that hinder the proliferation of HSI. To overcome this limitation, novel HSI architectures strive to minimize the strict requirements of HSI by introducing computation into the acquisition process.

Sampling and reconstructing signals from a union of linear subspaces

open access: yes, 2011
In this note we study the problem of sampling and reconstructing signals which are assumed to lie on or close to one ofseveral subspaces of a Hilbert space.
