粒度测定是在不精确分割图像目标的基础上，确定图像中的目标分布情况和大小，这对于粗略地描述一幅图像的性质和获取图像信息是很重要的。本程序注释易懂，可以实现。-Determination of particle size is based on the inaccurate image of the target partition, the target image is determined, and size distribution, it is very important for a more general descr iption of the nature of the image and the captured image information. The program notes to understand, can be achieved.
