Video denoising via empirical bayesian estimation of space-time patches

P Arias, JM Morel - Journal of Mathematical Imaging and Vision, 2018 - Springer
In this paper we present a new patch-based empirical Bayesian video denoising algorithm.
The method builds a Bayesian model for each group of similar space-time patches. These …

Dynamic low-light imaging with quanta image sensors

Y Chi, A Gnanasambandam, V Koltun… - Computer Vision–ECCV …, 2020 - Springer
Imaging in low light is difficult because the number of photons arriving at the sensor is low.
Imaging dynamic scenes in low-light environments is even more difficult because as the …

Accurate transmission estimation for removing haze and noise from a single image

Q Wu, J Zhang, W Ren, W Zuo… - IEEE transactions on …, 2019 - ieeexplore.ieee.org
