可以提取出图像中的红色信息，坐标空间变换（直角坐标系到极坐标系），彩色模型变换（RGB到HSI）-Red information can be extracted in the image coordinate space transform (Cartesian coordinates to polar coordinates), color model transformation (RGB to HSI)

HSI颜色模型到RGB颜色模型的相互转换，已经写成函数形式，直接调用即可。转换结果非常理想。-HSI color model to the RGB color model conversion, has been written in functional form, can be called directly. Conversion results are very satisfactory.
