On-Chip Compressive Sensing with a Single-Photon Avalanche Diode Array [PDF]

open access: yesSensors, 2023
Single-photon avalanche diodes (SPADs) are novel image sensors that record photons at extremely high sensitivity. To reduce both the required sensor area for readout circuits and the data throughput for SPAD array, in this paper, we propose a snapshot ...

Sparse Signal Representation, Sampling, and Recovery in Compressive Sensing Frameworks

open access: yesIEEE Access, 2022
Compressive sensing allows the reconstruction of original signals from a much smaller number of samples as compared to the Nyquist sampling rate. The effectiveness of compressive sensing motivated the researchers for its deployment in a variety of ...

Deep Sensing for Compressive Video Acquisition

open access: yesSensors, 2023
A camera captures multidimensional information of the real world by convolving it into two dimensions using a sensing matrix. The original multidimensional information is then reconstructed from captured images.

Wideband Spectrum Sensing: A Bayesian Compressive Sensing Approach

open access: yesSensors, 2018
Sensing the wideband spectrum is an important process for next-generation wireless communication systems. Spectrum sensing primarily aims at detecting unused spectrum holes over wide frequency bands so that secondary users can use them to meet their ...

Airborne Single-Pass Multi-Baseline InSAR Layover Separation Method Based on Multi-Look Compressive Sensing

open access: yesApplied Sciences, 2022
Due to the small number of baselines (2–3), the traditional L1 norm compressive sensing method for layover solution in InSAR has poor separation ability and height estimation stability and a long operation time.

A secure image permutation–substitution framework based on chaos and compressive sensing

open access: yesInternational Journal of Distributed Sensor Networks, 2020
Existing secure image acquisition works based on compressive sensing, viewing compressive sensing–based imaging system as a symmetric cryptosystem, can only achieve asymptotic spherical security denoting that the ciphertext only leaks information about ...
