Compressive Sampling for Array Cameras [PDF]

open access: yesSIAM Journal on Imaging Sciences, 2021
While design of high-performance lenses and image sensors has long been the focus of camera development, the size, weight, and power of image data processing components are currently the primary barriers to radical improvements in camera resolution. Here we show that deep learning--aided compressive sampling can reduce operating power on camera head ...

An Introduction To Compressive Sampling [PDF]

open access: yesIEEE Signal Processing Magazine, 2008
Conventional approaches to sampling signals or images follow Shannon's theorem: the sampling rate must be at least twice the maximum frequency present in the signal (Nyquist rate). In the field of data conversion, standard analog-to-digital converter (ADC) technology implements the usual quantized Shannon representation - the signal is uniformly ...

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.

Estimation of LFM signal parameters using RD compressed sampling and the DFRFT dictionary

open access: yesEURASIP Journal on Advances in Signal Processing, 2023
In this paper, a method combining random demodulator (RD) and discrete fractional Fourier transform (DFRFT) dictionary is suggested to directly estimate the parameters of linear frequency modulation (LFM) signals from compressed sampling data. First, the

Compressed sensing applied to modeshapes reconstruction [PDF]

open access: yes, 2011
Modal analysis classicaly used signals that respect the Shannon/Nyquist theory. Compressive sampling (or Compressed Sampling, CS) is a recent development in digital signal processing that offers the potential of high resolution capture of physical ...

LPI Radar Waveform Recognition Based on Multi-Branch MWC Compressed Sampling Receiver

open access: yesIEEE Access, 2018
In this paper, a new wideband digital receiver based on the modulated wideband converter compressed sampling (CS) system is proposed to replace a conventional wideband digital receiver, solve the cross-channel signal problem, and achieve intra-pulse ...

Image Encryption Scheme Based on Multiscale Block Compressed Sensing and Markov Model

open access: yesEntropy, 2021
Many image encryption schemes based on compressed sensing have the problem of poor quality of decrypted images. To deal with this problem, this paper develops an image encryption scheme by multiscale block compressed sensing. The image is decomposed by a

Compressive Sampling of Binary Images [PDF]

open access: yes2008 Congress on Image and Signal Processing, 2008
Compressive sampling is a novel framework that exploits sparsity of a signal in a transform domain to perform sampling below the Nyquist rate. In this paper, we apply compressive sampling to reduce the sampling rate of binary images. A system is proposed whereby the image is split into non-overlapping blocks of equal size and compressive sampling is ...
