Obstacles detection in foggy environment
In this paper, we propose a novel method of object detection in bad weather conditions like Fog and smoke. It is based on statistical model of dark channel prior to estimate the thickness of the haze and physics based image restoration approach. Further applying simple image enhancement techniques improve the visibility of an obstacle in the line of sight. Using this prior with this imaging mod...
متن کاملFoggy days and dry nights determine crown-level water balance in a seasonal tropical Montane cloud forest.
The ecophysiology of tropical montane cloud forest (TMCF) trees is influenced by crown-level microclimate factors including regular mist/fog water inputs, and large variations in evaporative demand, which in turn can significantly impact water balance. We investigated the effect of such microclimatic factors on canopy ecophysiology and branch-level water balance in the dry season of a seasonal ...
متن کاملFoggy perception slows us down
Visual speed is believed to be underestimated at low contrast, which has been proposed as an explanation of excessive driving speed in fog. Combining psychophysics measurements and driving simulation, we confirm that speed is underestimated when contrast is reduced uniformly for all objects of the visual scene independently of their distance from the viewer. However, we show that when contrast ...
متن کاملYaws in Manchester.
Yaws is found in underdeveloped areas lying between the Tropics of Cancer and Capricorn. It is a contagious treponematosis usually affecting non-white communities living in primitive and impoverished circumstances in areas of heavy rainfall, lush vegetation, and high humidity. Infection is probably spread by direct contact in childhood and is facilitated by abrasions of the sweat-sodden skin un...
