Enhancing Visibility Range in Foggy Weather by Contrast Stretched CLAHE (CS- CLAHE)

Abstract

Road accidents are becoming a very common problem due to unfavorable weather conditions like rain, fog, and pollution etc. The reason behind such accident is due to poor visibility outside, on the roads and hence driving becomes a problematic issue. Poor visibility becomes due to atmospheric trend originated such as fog, mist originated by small particles in the air such as dust, smoke or moisture, which reduces the visibility of the outdoor scenes. In this paper we are suggesting a Contrast Stretched CLAHE (CS-CLAHE) which will enhance the visibility of outside environment to take necessary precautions for prevention and avoiding the accidents. In the situation of real time streaming, there is a sequence of multiple frames per second, which are to be processed for enhancing the streaming. Therefore, this paper will discuss as a first step: how to enhance a single image and at second stage, processing of multiple images of streaming in parallel processing environment. For fast processing FPGA model is suggested.
