IIT Madras develops technology to remove haze in surveillance camera images


Indian Institute of Technology Madras has developed enhanced image processing techniques to mitigate the impact of haze on images captured by surveillance cameras. This can prove crucial in helping law enforcement agencies solve crimes and help the common public as many communities are now installing CCTVs to safeguard themselves.

This research can also be applied to self-driving and autonomous vehicles as they also require high-quality images taken by cameras for efficient and safe navigation, especially in urban areas. Although CCTV cameras are helpful in providing evidence of a crime, the quality of the image is negatively impacted on foggy or hazy days. The visibility of a camera goes down on such hazy days, rendering it difficult to take a clear picture or to capture a clear video of a scene.
