说明：  基于图像识别的整精米自动检测 检测出图中的碎米，并在相应的米粒上打上标志。 对图像进行预处理,把米粒图像变成二值图像,根据区域内部像素的连通性，将不同的区域赋予不同的标记,计算出单个米粒所占的像素
(Based on Image Recognition milled rice automatically detect detect the broken map, and marked with the corresponding symbol on a grain of rice. The image preprocessing, the image into a binary image grain, according to the connectivity within the region pixels will be different in different regions of the mark given to calculate the share of a single grain of rice pixels)
