A common problem for imaging in the atmosphere is fog and atmospheric turbulence. Over the years, many researchers have provided insight into the physics of either the fog or turbulence but not both. Most recently, researchers have proposed methods t

In our previous work, we showed how to employ a single image defogging method by using a parallel SIMD architecture on a System on Chips (SoC). In this work, owing to improvements of hardware, we provide an update to this implementation with more opt

This paper makes an investigation of the dehazing effects on image and video coding for surveillance systems. The goal is to achieve good dehazed images and videos at the receiver while sustaining low bitrates (using compression) in the transmission

The increase of video cameras on phones, privately owned unmanned aerial vehicles, and now automobiles increase the demand for improved subjective quality in hazy and foggy weather. The presence of fog and haze reduce the local contrast of scenes whi

The knowledge of the turbulence strength in the atmosphere is important for many applications. Imagery in the atmosphere experience significant blur when the turbulence is strong. This can be automatically improved (without user intervention) if the

This paper presents a new approach to estimate fog-free images from stereo foggy images. We investigate a new way to estimate transmission by computing the scattering coefficient and depth information of a scene. However, most existing visibility res
