Compressive sampling and reconstruction in shift-invariant spaces associated with the fractional Gabor transform

open access: yesDefence Technology, 2022
In this paper, we propose a compressive sampling and reconstruction system based on the shift-invariant space associated with the fractional Gabor transform.

Compressed sensing MRI with Bayesian dictionary learning [PDF]

open access: yes2013 IEEE International Conference on Image Processing, 2013
We present an inversion algorithm for magnetic resonance images (MRI) that are highly undersampled in k-space. The proposed method incorporates spatial finite differences (total variation) and patch-wise sparsity through in situ dictionary learning. We use the beta-Bernoulli process as a Bayesian prior for dictionary learning, which adaptively infers ...

Adaptive Localization in Wireless Sensor Network through Bayesian Compressive Sensing

open access: yesInternational Journal of Distributed Sensor Networks, 2015
The estimation of the localization of targets in wireless sensor network is addressed within the Bayesian compressive sensing (BCS) framework. BCS can estimate not only target locations but also noise variance of the environment.

Synthetic aperture sonar imaging using compressive sensing and an ultrasound transducer array [PDF]

open access: yes, 2013
Includes bibliographical references.Compressive sensing (CS) also known as compressive sampling is a technique used to reconstruct or recover the full-length of a signal with only a few non-adaptive measurements.

On the Use of Structured Prior Models for Bayesian Compressive Sensing of Modulated Signals

open access: yesApplied Sciences, 2021
The compressive sensing (CS) of mechanical signals is an emerging research topic for remote condition monitoring. The signals generated by machines are mostly periodic due to the rotating nature of its components.

Compressive Sensing Approaches for Autonomous Object Detection in Video Sequences [PDF]

open access: yes, 2015
Video analytics requires operating with large amounts of data. Compressive sensing allows to reduce the number of measurements required to represent the video using the prior knowledge of sparsity of the original signal, but it imposes certain conditions

Compressive Sensing for PAN-Sharpening [PDF]

open access: yes, 2011
Based on compressive sensing framework and sparse reconstruction technology, a new pan-sharpening method, named Sparse Fusion of Images (SparseFI, pronounced as sparsify), is proposed in [1].

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy

open access: yesAdvanced Engineering Materials, EarlyView.
Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).

Autofocus Bayesian compressive sensing for multipath exploitation in urban sensing [PDF]

open access: yes2015 IEEE International Conference on Digital Signal Processing (DSP), 2015
Exploitation of group sparsity under multipath propagation enables high-resolution ghost-free imaging in urban sensing and through-the-wall radar imaging applications. Multipath exploitation schemes typically require exact prior information of the indoor scene layout and transceiver locations to eliminate ghosts targets.
