Contrast restoration of weather degraded images
TL;DR: A physics-based model is presented that describes the appearances of scenes in uniform bad weather conditions and a fast algorithm to restore scene contrast, which is effective under a wide range of weather conditions including haze, mist, fog, and conditions arising due to other aerosols.
Journal ArticleDOI
Vision and the Atmosphere
TL;DR: This work studies the visual manifestations of different weather conditions, and model the chromatic effects of the atmospheric scattering and verify it for fog and haze, and derives several geometric constraints on scene color changes caused by varying atmospheric conditions.

Instant dehazing of images using polarization
TL;DR: This work analyzes the image formation process, taking into account polarization effects of atmospheric scattering, and invert the process to enable the removal of haze from images, and obtains a great improvement of scene contrast and correction of color.
Proceedings ArticleDOI
Blind Haze Separation
TL;DR: An approach for blindly recovering the parameter needed for separating the airlight from the measurements, thus recovering contrast, with neither user interaction nor existence of the sky in the frame is derived, which eases the interaction and conditions needed for image dehazing.

Terahertz detectors and focal plane arrays
Antoni Rogalski,Fiodor F. Sizov +1 more
TL;DR: Terahertz (THz) technology is one of emerging technologies that will change our life as mentioned in this paper, however, the realization of THz emitters and receivers is a challenge because the frequencies are too high for conventional electronics and the photon energies are too small for classical optics.
