Suppression of local haze variations in MERIS images over turbid coastal waters for retrieval of suspended sediment concentration [PDF]

open access: yes, 2010
Atmospheric correction over turbid waters can be problematic if atmospheric haze is spatially variable. In this case the retrieval of water quality is hampered by the fact that haze variations could be partly mistaken for variations in suspended sediment

Image haze removal based on rolling deep learning and Retinex theory

open access: yesIET Image Processing, 2022
Multispectral remote sensing images are a very important data source, but its acquisition process is often affected by haze weather and other factors, resulting in the decline of image quality, blurred details and poor visual effect, which seriously ...

Haziness Degree Evaluator: A Knowledge-Driven Approach for Haze Density Estimation

open access: yesSensors, 2021
Haze is a term that is widely used in image processing to refer to natural and human-activity-emitted aerosols. It causes light scattering and absorption, which reduce the visibility of captured images. This reduction hinders the proper operation of many

The variability of volatile organic compounds during a persistent fog-haze episode

open access: yesFrontiers in Environmental Science, 2022
A persistent fog-haze process associated with high pollution occurred in the northern suburbs of Nanjing from November to December 2013. Based on the comprehensive chemical and microphysical observations during the intense observation period, the ...

Single Image Haze Removal Based on a Simple Additive Model With Haze Smoothness Prior [PDF]

open access: yesIEEE Transactions on Circuits and Systems for Video Technology, 2022
Single image haze removal, which is to recover the clear version of a hazy image, is a challenging trask in computer vision. In this paper, an additive haze model is proposed to approximate the hazy image formation process. In contrast with the traditional optical model, it regards the haze as an additive layer to a clean image.

Robust Single-Image Haze Removal Using Optimal Transmission Map and Adaptive Atmospheric Light

open access: yesRemote Sensing, 2020
Haze removal is an ill-posed problem that has attracted much scientific interest due to its various practical applications. Existing methods are usually founded upon various priors; consequently, they demonstrate poor performance in circumstances in ...

Seasonal distributions of fine aerosol sulfate in the North American Arctic basin during TOPSE [PDF]

open access: yes, 2003
We used the mist chamber/ion chromatography technique to quantify fine aerosol SO4=(\u3c2.7 μm) in the Arctic during the Tropospheric Ozone Production about the Spring Equinox Experiment (TOPSE) with about 2.5 min time resolution.

Haze removal concept in remote sensing [PDF]

open access: yesApplied Mathematical Sciences, 2016
Atmospheric haze causes visibility to drop, therefore affecting data acquired using optical sensors on board remote sensing satellites. Haze modifies the spectral signatures of land cover classes and reduces classification accuracy so causing problems to users of remote sensing data.
