完成图像RGB到HSV的转换，比较自定义函数转换和使用opencv提供函数直接转换的结果。可用于研究H，S，V分量的范围等,Image RGB to HSV conversion, more-defined functions and use the conversion function opencv provide direct conversion results. Can be used to study H, S, V component of the scope of

RGB 转换到HSI 里面用了opencv的cvGet2D函数,RGB to HSI conversion opencv spent inside the function cvGet2D

基于OPENCV的色调调整，将图像进行色彩空间转换RGB 转换到HSV 对H分量进行调节-Hue adjust depend on OPENCV. Firstly,converting the picture space RBG to HSV. Then, adjust the value of H.Finally convert the picture back to the RGB space.

本程序使用opencv将RGB转换成HSV颜色空间，并且读取H通道图像。-This program uses opencv RGB to HSV color space , and to read the H-channel image .
