IDE: Image Dehazing and Exposure Using an Enhanced Atmospheric Scattering Model
IEEE Transactions on Image Processing, 2021Atmospheric scattering model (ASM) is one of the most widely used model to describe the imaging processing of hazy images. However, we found that ASM has an intrinsic limitation which leads to a dim effect in the recovered results. In this paper, by introducing a new parameter, i.e., light absorption coefficient, into ASM, an enhanced ASM (EASM) is ...

Single hazy image restoration using robust atmospheric scattering model
Signal Processing, 2020Abstract Images captured in unfavorable weather usually exhibit poor visibility, which results from scattering and absorption that the propagated light suffers in the atmosphere. To improve the quality of degraded images, multitudes of algorithms have been exploited based on traditional atmospheric scattering model. However, in the traditional model,

Single image haze removal based on the improved atmospheric scattering model
Neurocomputing, 2017Abstract In this paper, we propose an improved atmospheric scattering model (IASM) to overcome the inherent limitation of the traditional atmospheric scattering model. Based on the IASM, a fast single image dehazing algorithm is also presented. In this algorithm, by constructing a linear model between the transmission and the haze aware density ...

Modeling and Rendering of the Atmosphere Using Mie‐Scattering
Computer Graphics Forum, 1997This paper presents a method for rendering of the atmosphere by means of Mie‐scattering. The method is based on a concentric atmospheric model, which is divided into four submodels: for clear air, aerosol, ozone, and rain. In order to simulate and visualize the various atmospheric effects, each of these submodels can be parameterized by the user as ...

On inhomogeneous scattering models of Titan's atmosphere
Icarus, 1979Podolak and Danielson (1977) discussed the homogeneous model of Titan's atmosphere with the dust and gas uniformly mixed. They were able to reproduce the equivalent widths of the CH4 bands at 4680 and 5430 A but failed to agree with the observations in the near infrared.

Pure and Applied Geophysics, 2020
In this work, we show that large-scale processes of the long-range propagation and scattering of infrasound signals in stratospheric and thermospheric waveguides are to some extent similar to the smaller scale processes of waveguide propagation and scattering of acoustic signals in stably stratified ABL.

Multiple scattering theory for modeling sonic booms in atmospheric turbulence
The Journal of the Acoustical Society of America, 2023Sonic booms are often modeled using Burgers equations accounting for dominant propagation effects. Scattering effects of turbulence, however, have not been incorporated into such equations, although these effects are ubiquitous in measured sonic booms.

Quasiwavelet models of sound scattering by atmospheric turbulence
The Journal of the Acoustical Society of America, 2002Quasiwavelet (QW) representations of turbulence are composed of self-similar, localized, eddylike structures. The QW functions are not true wavelets, in that they do not form a mathematically complete basis or have zero mean. Nevertheless, they appear to be very useful for applications involving scattering and propagation of sound waves. In this paper,
