Visibility: Science and regulation

JG Watson - Journal of the Air & Waste Management Association, 2002 - Taylor & Francis
Abstract The 1999 Regional Haze Rule provides a context for this review of visibility, the
science that describes it, and the use of that science in regulatory guidance. The scientific …

Polarization-based vision through haze

YY Schechner, SG Narasimhan, SK Nayar - Applied optics, 2003 - opg.optica.org
We present an approach for easily removing the effects of haze from passively acquired
images. Our approach is based on the fact that usually the natural illuminating light scattered …

Recovery of underwater visibility and structure by polarization analysis

YY Schechner, N Karpel - IEEE Journal of oceanic engineering, 2005 - ieeexplore.ieee.org
Underwater imaging is important for scientific research and technology as well as for
popular activities, yet it is plagued by poor visibility conditions. In this paper, we present a …

YY Schechner, N Karpel - … of the 2004 IEEE Computer Society …, 2004 - ieeexplore.ieee.org
Underwater imaging is important for scientific research and technology, as well as for
popular activities. We present a computer vision approach which easily removes …

A fast semi-inverse approach to detect and remove the haze from a single image

CO Ancuti, C Ancuti, C Hermans, P Bekaert - Asian Conference on …, 2010 - Springer
In this paper we introduce a novel approach to restore a single image degraded by
atmospheric phenomena such as fog or haze. The presented algorithm allows for fast …

[图书][B] Seeing black and white

A Gilchrist - 2006 - books.google.com
How the human visual system determines the lightness of a surface, that is, its whiteness,
blackness, or grayness, remains--like vision in general--a mystery. In fact, we have not even …

Image dehazing using polarization effects of objects and airlight

S Fang, XS Xia, X Huo, CW Chen - Optics express, 2014 - opg.optica.org
The analysis of polarized filtered images has been proven useful in image dehazing.
However, the current polarization-based dehazing algorithms are based on the assumption …

Haze effect removal from image via haze density estimation in optical model

CH Yeh, LW Kang, MS Lee, CY Lin - Optics express, 2013 - opg.optica.org
Images/videos captured from optical devices are usually degraded by turbid media such as
haze, smoke, fog, rain and snow. Haze is the most common problem in outdoor scenes …

Skyless polarimetric calibration and visibility enhancement

E Namer, S Shwartz, YY Schechner - Optics express, 2009 - opg.optica.org
Outdoor imaging in haze is plagued by poor visibility. A major problem is spatially-varying
reduction of contrast by airlight, which is scattered by the haze particles towards the camera …

Polarization: Beneficial for visibility enhancement?

T Treibitz, YY Schechner - 2009 IEEE Conference on Computer …, 2009 - ieeexplore.ieee.org
When imaging in scattering media there is a need to enhance visibility. Some approaches
have used polarized images in this context with apparent success. These methods take …
