为实现对图像更好的阈值分割，针对原始色差变换存在的同色异值、异色同值的问题，基于HSI彩色空间色差变换，提出正余弦交叉法（SCCM）取参考点。该变换方法是根据各点色调正余弦值计算总体正、余弦均值，再由此求得对应的色调值。方法能够根据不同图像自适应地计算色差变换的参考点，使得变换后的灰度图有较好的灰度分布，为阈值分割提供更好的分割对象，提高分割质量。

In HSI color space, there’re some problems with original color difference transformation such as the same color may be different values or different color with the same value. For solving the problem and achieving better effect of image threshold segmentation, the Sine &Cosine Cross Method(SCCM)is proposed to calculate the reference point based on original color difference transformation. This method can calculate the reference point of the transformation adaptively according to different image, which makes the grayscale image a better grayscale distribution, provides better segmented object, improves segmentation effect.
