本设计是针对第二题采用了两种算法用来识别各种水果。第一种算法是质心法，第二种方法是相关匹配法。

质心法

一．算法思想

质心法的优点在于图像经过任何旋转后，图像边缘到质心的距离求和始终为一个固定值，这样利用这一个特性，就可以辨识出各个图像。

-This design is the second title for the two algorithms used to identify a variety of fruits. The first is a qualitative-force algorithm, the second method is related to matching.

Quality-force

1. Algorithm thinking

The advantages of quality-force any rotating images, the image edge to the distance from the center of mass is always a fixed sum of value, so to make use of this characteristic, we can identify the various images.
