Images captured in low-light environments suffer from serious degradation due to insufficient
light, leading to the performance decline of industrial and civilian devices. To address the …

Robust object detection under photon-limited conditions is crucial for applications such as
night vision, surveillance, and microscopy, where the number of photons per pixel is low due …

The quanta image sensor (QIS) is a photon-counting image sensor that has been
implemented using different electron devices, including impact ionization-gain devices, such …

This letter reports a 16.7 Mpixel, 3D-stacked backside illuminated Quanta Image Sensor
(QIS) with 1.1 μm-pitch pixels which achieves 0.19 e-rms array read noise and 0.12 e-rms …

Low-light imaging on mobile devices is typically challenging due to insufficient incident light
coming through the relatively small aperture, resulting in low image quality. Most of the …

The one-bit quanta image sensor (QIS) is a photon-counting device that captures image
intensities using binary bits. Assuming that the analog voltage generated at the floating …

Conventional digital cameras typically accumulate all the photons within an exposure period
to form a snapshot image. It requires the scene to be quite still during the imaging time …

Image deblurring in photon-limited conditions is ubiquitous in a variety of low-light
applications such as photography, microscopy and astronomy. However, the presence of the …

This paper presents a feature descriptor using Histogram of Oriented Mosaic Gradient
(HOMG) that extracts spatial-spectral features directly from mosaic spectral images. Spectral …

The signal-to-noise ratio (SNR) is a fundamental tool to measure the performance of an
image sensor. However, confusions sometimes arise between the two types of SNRs. The …
