The guided filter can be used as an edge-preserving smoothing operator like the popular bilateral filter, but has better behaviors near edges. The guided filter is also a more generic concept beyond smoothing: it can transfer the structures of the gu

导向滤波器，可以对图像实现增强、渐变处理、保边平滑等作用，可以在去雾算法中使用对图像的透射率进行优化。-guided filter,you would use it to enhance the image,image feathering,smooth,and to optimize the transmission map when dehazeing the image.

引导滤波的源程序，可以实现引导滤波图像增强和图像平滑。是目前较为热门的图像滤波算法，滤波效果好，运行速度快。-Guide filtered source.It can realize image enhancement and image smoothing. A popular image filtering algorithm with good filtering effect and fast running speed.

快速加权引导滤波，对引导滤波加速，但是是以损失精度为代价(Fast weighted bootstrap filtering accelerates the bootstrap filtering, but at the expense of loss accuracy)
