In view of the classic dark channel prior algorithm for image to fog will exist a splash and appear the "white",the problem of the missing details,the article adopts oriented filtering and K threshold method to optimize the combination,and use the image quality evaluation method for the optimized algorithm for testing and comprehensive analysis.The optimized algorithm are verified through the experiment to fog effect is better than the original algorithm.
Key words
