Haze Removal of Secure Remote Surveillance System

A reliable method for dehazing image and video was proposed. The goal is to achieve good dehazed images and videos with proper security at the receiver side. The image was dehazed by dark channel prior. The system based on fast single image dehazing and here the codecs used is joint photographic expert group. Then the compressed image is extended to compressed video, by using codecs H.264. Then by considering the dehazing effects before or after compression, the coding artifacts and motion estimation were investigated. Before compression produce better dehazing performance with fewer artifacts and better coding efficiency than after compression. By using these methods, the thickness of haze and haze free images and videos can be estimated directly. Then a watermark is added for digital right management and the watermarked image and videos is encrypted with a fast and reliable light weight algorithm. This image and video is transmitted to the receiver side. At the receiver side, the use with correct key can decrypt the image and the image will be watermarked with watermark symbol, the watermarked image can be used to trace illegal distribution. Thus this system produces a dehazed image and video with high secure and fast transmission.
