首先进行边缘检测，然后进行填充。然后进行开运算，可以使一些轻微连着的米粒分开来。然后是遍历图片，把各米粒进行标号，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。-First, edge detection, and then filled. Then open computing can make some minor attached rice grains to separate. Then traverse the pictures, label each grain of rice, start from a small to a big label. Each pixel of each rice grain is the same value, each pixel value of the i th groats are i. Which uses a queue array simulation. The total number of the largest grain of rice label is a grain of rice. Finally, traverse again the image array, you can find the area of ​ ​ each grain of rice.
