FAST SINGLE IMAGE HAZE REMOVAL AND DATA HIDI NG SYSTEM

Haze brings trouble to many computer vision and computer graphics applications. Single image haze removal is a challenging problem. In order to solve this problem a simple but powerful method to remove haze from single image is proposed. It uses a color a ttenuation prior model for haze removal. A linear model is created for modeling the depth of the scene and using depth map we can easily estimate transmission map and outlook radi ance, thus effectively removing haze from single image. In the dehazed image some confidential data like time at which photos are taken and temperature of the place from where the photos are taken can be mad e hidden and this secret message can be recovered whenever necessary.
