Virtual-modems

this program contain a thresholding method to threshold images

说明：  Image Segmentation on sample images.

通过ssr算法，在YCBCR空间上 对Y分量单独处理，来实现对图像光照不均匀处理，效果很好 可以继续改进(By ssr algorithm, YCBCR space on the Y component alone, to achieve uniform illumination of image processing, the effect is very good to continue to improve)
