Imaging spectroscopy involves the sensing of a large amount of spatial information across a
multitude of wavelengths. Conventional approaches to hyperspectral sensing scan adjacent …

The capability of an active spacecraft to accurately estimate its relative position and attitude
(pose) with respect to an active/inactive, artificial/natural space object (target) orbiting in …

Visual quality of color images is an important aspect in various applications of digital image
processing and multimedia. A large number of visual quality metrics (indices) has been …

By leveraging metamaterials and compressive imaging, a low-profile aperture capable of
microwave imaging without lenses, moving parts, or phase shifters is demonstrated. This …

The mathematical theory of compressed sensing (CS) asserts that one can acquire signals
from measurements whose rate is much lower than the total bandwidth. Whereas the CS …

Most of the image encryption algorithms are the private-key cryptosystem, in which the
encryption process and the decryption process employ the same keys. To enhance the …

The recent mathematical concept of compressed sensing (CS) asserts that a small number
of well-chosen measurements can suffice to reconstruct signals that are amenable to sparse …

In this paper, we make contact with the field of compressive sensing and present a
development and generalization of tools and results for reconstructing irregularly sampled …

The generalized linear model (GLM), where a random vector x is observed through a noisy,
possibly nonlinear, function of a linear transform output z= Ax, arises in a range of …

Single-shot coded-aperture optical imaging physically captures a code-aperture-modulated
optical signal in one exposure and then recovers the scene via computational image …
