Journal ArticleDOI
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.
Proceedings ArticleDOI
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
Vision in bad weather
TL;DR: This work begins by studying the visual manifestations of different weather conditions, and develops models and methods for recovering pertinent scene properties, such as three-dimensional structure, from images taken under poor weather conditions.
Proceedings ArticleDOI
Chromatic framework for vision in bad weather
TL;DR: This paper develops a geometric framework for analyzing the chromatic effects of atmospheric scattering, and derives several geometric constraints on scene color changes, caused by varying atmospheric conditions.
