| Abstract | It is important to guarantee that images circulating in mobile cloud of smart city are not obscured by fog. Based on near-infrared's ability to penetrate fog, this paper puts forward a 2-step real-time defog model for camera: putting forward the infrared - blue light intensity difference factor and using dark channel prior to estimate haze distribution map; fusing near-infrared and visible information based on the haze distribution and then, adopting downsampling, fast fuzz algorithm and fast guided filter to remove the artificial effect and improve the efficiency. This simple and efficient method is rid of complicated physical models and cumbersome manual operations while provides results with richer color, sharper details than other algorithms, achieving accuracy, real-time, fidelity and automation at the same time. Camera based on this model is an excellent multimedia application for mobile cloud of smart city. |
