Generative Quanta Color Imaging

no code implementations28 Mar 2024 Vishal Purohit, Junjie Luo, Yiheng Chi, Qi Guo, Stanley H. Chan, Qiang Qiu

In this paper, we explore the possibility of generating a color image from a single binary frame of a single-photon camera.

Spatio-Temporal Turbulence Mitigation: A Translational Perspective

1 code implementation8 Jan 2024 Xingguang Zhang, Nicholas Chimitt, Yiheng Chi, Zhiyuan Mao, Stanley H. Chan

Building upon the intuitions of classical TM algorithms, we present the Deep Atmospheric TUrbulence Mitigation network (DATUM).

Kernel Diffusion: An Alternate Approach to Blind Deconvolution

no code implementations4 Dec 2023 Yash Sanghvi, Yiheng Chi, Stanley H. Chan

Blind deconvolution problems are severely ill-posed because neither the underlying signal nor the forward operator are not known exactly.

Spatially Varying Exposure with 2-by-2 Multiplexing: Optimality and Universality

no code implementations30 Jun 2023 Xiangyu Qu, Yiheng Chi, Stanley H. Chan

The advancement of new digital image sensors has enabled the design of exposure multiplexing schemes where a single image capture can have multiple exposures and conversion gains in an interlaced format, similar to that of a Bayer color filter array.

HDR Imaging with Spatially Varying Signal-to-Noise Ratios

no code implementations CVPR 2023 Yiheng Chi, Xingguang Zhang, Stanley H. Chan

For HDR imaging in photon-limited situations, the dynamic range can be enormous and the noise within one exposure is spatially varying.

Scattering and Gathering for Spatially Varying Blurs

no code implementations10 Mar 2023 Nicholas Chimitt, Xingguang Zhang, Yiheng Chi, Stanley H. Chan

A spatially varying blur kernel $h(\mathbf{x},\mathbf{u})$ is specified by an input coordinate $\mathbf{u} \in \mathbb{R}^2$ and an output coordinate $\mathbf{x} \in \mathbb{R}^2$.
