RGB采集卡应用开发程序示例程序源代码，有一定的参考价值-RGB capture card application development process sample program source code, there is some reference value

用多项式回归的方法编程实现了从设备相关颜色空间RGB到设备无关颜色空间Lab之间的转换。-Polynomial regression method with programming from the device-dependent RGB color space to device-independent color space conversion between Lab.

实现了RGB空间转换到HSI空间，并分别求出S分量（饱和度）、I分量（亮度、光强）-Implements the RGB space to HSI space, and respectively calculate S components (saturation), I (brightness, light intensity)
