Q3_1

计算图像中的欧拉数，经典代码，采用matlab实现，可以熟悉欧拉数的求法，及相关MATLAB函数的用法，带图片可测试。(calculated image of Euler number, classic code using Matlab realized, could familiar with the Euler number for the law, MATLAB functions and related usage, with pictures can be tested.)

Fuzzy logic is a form of many-valued logic or probabilistic logic it deals with reasoning that is approximate rather than fixed and exact. Compared to traditional binary sets (where variables may take on true or false values) fuzzy logic variables may have a truth value that ranges in degree between 0 and 1. Fuzzy logic has been extended to handle the concept of partial truth, where the truth value may range between completely true and completely false.[1] Furthermore, when linguistic variables are used, these degrees may be managed by specific functions.
