图像处理 求出图像中米粒个数以及各米粒的大小
首先进行边缘检测，然后填充，之后进行开运算，可以使一些轻微连接着的米粒分开。然后遍历图片，把各个米粒进行标号，从1开始从小到大标号。每个米粒的各像素点值相同，第i个米粒的各像素点值均为i。其中采用了队列，用数组模拟。最大的米粒标号便是米粒的总个数。最后，遍历一遍图像数组，便可求出各米粒的面积。(image processing　 The number of rice grains and the size of each grain were calculated

First edge detection, and then fill, and then open operations, can be slightly connected to the separation of rice grains. Then go through the pictures, label each grain, from 1 to small label. The pixel value of each rice grain is the same, each pixel value of the I rice was I. The queue is used, and the array is simulated. The largest grain mark is the total number of grains. Finally, the area of each rice grain can be calculated by traversing the image array.)
