用Reinhard算法实现了图像之间色彩的迁移，程序为Reinhard.m；并对该算法进行了改进，程序为Reinhard improved.m-color transfer using Reinhard method.

将低动态范围图像通过色调映射技术转换为高动态范围图像，对图像的亮度通道进行加强，该算法是reinhard代码进行实现的。(The low dynamic range image is transformed into high dynamic range image by hue mapping technology, and the brightness channel of the image is enhanced. The algorithm is implemented by Rein
