基于图像识别的整精米自动检测研究

本文采取动态阈值分割，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，再通过先期计算的整精米长度／面积比换算出米粒长度，最后根据米粒长度判断整精米和碎米。研究结果表明，该算法的自动检测与人工检测相关性大于99％，可用于整精米的自动检测。

Head Rice Automatic Detection System Based on Image Recognition

The following is the presented detection procedure in this article: Adopt dynamic threshold disintegrating and change the head rice into binary images;according to the connection of the internal pixel,attach different labels to different regions and calculate the pixel which one head rice takes;then through the previous length/area ratio of head rice get the length;finally recognize the head rice and broken rice.The datum shows that the correlation between the results from this automatic detection process and manual detecting system is over 99%.This detection procedure surely can be used in the automatic detecting system.
