Sampling for Snapshot Compressive Imaging

open access: yesIntelligent Computing, 2023
In this study, we compare interlaced and multiscale sampling of smooth manifolds for snapshot compressive imaging. With a particular focus on spectral, spatial, and temporal focal photographic imaging systems, we show that structured transformer networks

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 ...

Sub-Nyquist SAR via Quadrature Compressive Sampling with Independent Measurements

open access: yesRemote Sensing, 2019
This paper presents an efficient sampling system for the acquisition of synthetic aperture radar (SAR) data at sub-Nyquist rate. The system adopts a quadrature compressive sampling architecture, which uses modulation, filtering, sampling and digital ...

A reconfigurable real-time compressive-sampling camera for biological applications. [PDF]

open access: yesPLoS ONE, 2011
Many applications in biology, such as long-term functional imaging of neural and cardiac systems, require continuous high-speed imaging. This is typically not possible, however, using commercially available systems.

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 ...
