Single-pixel hyperspectral imaging (HSI) has received a lot of attention in recent years due
to its advantages of high sensitivity, wide spectral ranges, low cost, and small sizes. In this …

We investigate the problems of 1-D and 2-D signal recovery from subsampled Hadamard
measurements using Haar wavelet as a sparsity inducing prior. These problems are of …

In a single-pixel camera, an unknown object is sequentially illuminated by intensity patterns.
The total reflected or transmitted intensity is summed in a single-pixel detector from which …

Raman spectral imaging finds extensive application across diverse domains, including
medical science, pharmaceuticals, and chemical detection. Acquiring multidimensional …

Fourier transform interferometry (FTI) is an appealing hyperspectral (HS) imaging modality
for many applications demanding high spectral resolution, eg, in fluorescence microscopy …

Single Pixel (SP) imaging is now a reality in many applications, eg, biomedical ultrathin
endoscope and fluorescent spectroscopy. In this context, many schemes exist to improve the …

In typical single-pixel detection multiplexing, an unknown object is sequentially illuminated
with intensity patterns: the total signal is summed into a single-pixel detector and is then …

The idea of capturing hundreds to thousands images of an object, eg, biological specimen,
in different wavelengths has attracted decades of research under the name of HyperSpectral …

We study the problem of image recovery from subsampled Hadamard measurements using
Haar wavelet sparsity prior. This problem is of interest in, eg, computational imaging …
