Image Dehazing Using LiDAR Generated Grayscale Depth Prior

Sensors, 2022
In this paper, the dehazing algorithm is proposed using a one-channel grayscale depth image generated from a LiDAR point cloud 2D projection image. In depth image-based dehazing, the estimation of the scattering coefficient is the most important.

A Fast Single-Image Dehazing Algorithm Based on Dark Channel Prior and Rayleigh Scattering

IEEE Access, 2020
The scattering of atmospheric particles significantly alters images captured under hazy weather condition. Images appear distorted, blurry and low in contrast attenuation, which extensively affects computer vision systems.

Smaller Sensitivity of Precipitation to Surface Temperature Under Massive Atmospheres

Geophysical Research Letters, 2022
Precipitation and its response to forcing is an important aspect of planetary climate system. In this study, we examine the strength of precipitation in the experiments with different atmospheric masses and their response to surface warming, using three ...

Modeling of inelastically scattered radiation: Rotational Raman scattering in the spherical Earth’s atmosphere

Journal of Quantitative Spectroscopy and Radiative Transfer, 2021
Abstract This study presents an approximative approach to solve the radiative transfer equation accounting for the rotational Raman scattering in a spherical atmosphere. The solution is obtained employing the method of characteristics in combination with the discrete-ordinates technique and the forward-adjoint perturbation theory.

Fast and simple model for atmospheric radiative transfer [PDF]

, 2010
Radiative transfer models (RTMs) are of utmost importance for quantitative remote sensing, especially for compensating atmospheric perturbation. A persistent trade-off exists between approaches that prefer accuracy at the cost of computational complexity,

Single image dehazing via an improved atmospheric scattering model [PDF]

The Visual Computer, 2016
Under foggy or hazy weather conditions, the visibility and color fidelity of outdoor images are prone to degradation. Hazy images can be the cause of serious errors in many computer vision systems. Consequently, image haze removal has practical significance for real-world applications.

Effects of dust particle internal structure on light scattering [PDF]

Atmospheric Chemistry and Physics, 2015
There is a large variety of internal structures inside atmospheric dust particles, making them inherently inhomogeneous. Such structures may have a large effect on ground-level and atmospheric radiation.
