说明：  本文件为引导滤波算法的程序文件，为VC++编码，根据何凯明博士的文章《Guided Image Filtering》讲述的原理编写而成，具有很好的边缘保持特性，是作为作者在前一篇讲解去雾算法的文章《Single Image Haze Removal Using Dark Channel Prior》的补充，当然也可以用于其他的滤波算法中
(This document is a boot file filtering algorithm for VC++ coding, according to Dr. He Kaiming article " Guided Image Filtering" principle tells prepared, with good edge retention characteristics, as an explanation of the previous algorithm decontamination The article " Single Image Haze Removal Using Dark Channel Prior" supplement, of course, can also be used for other filtering algorithms)
