An Improved Hybrid Method for Defogging Single Image

In this article, we suggest a different method for addressing the issue of nighttime single image dehazing. Because landscape frequently includes several light sources, ambient lighting haze period is usually not globally isotropic. Existing dehazing algorithms have tried to treat these two zones using same prior assumptions. We propose novel blending approach resolving them in work. A channel difference guided filtering with contrast stretch presented estimate light, which creates spatially variable low-frequency passband that selectively retains high-frequency edge information.
