Hardware implementation of foghaze removal system

Abstract

The problem that we face when doing long distance photography or making of video is that the light reflected from a surface is scattered in the atmosphere before it reaches the camera and this is due to the presence of aerosols such as dust, mist and fumes which deflect light from its original course of propagation and this effect increases tremendously in the presence of fog or haze. Because of this, the image or video captured appears blur, faint and it lacks visual vividness. So the main aim of this project is to remove the effects of noise that is caused due to the presence of fog/haze from a real time video. The algorithm for the removal of effects of fog/haze is implemented on FPGA. The system first captures the corrupted video with fog/haze with the help of a camera, and then passes this video from the implemented algorithm which removes the effects of fog/haze from the video and in the end displays a clear video without the effects of fog/haze on the VGA monitor.
