提出了一种改进的模糊阈值选取方法 .针对传统的模糊阈值法隶属函数窗宽不容易确定的出发点 ,结合传统的易于实现的阈值选取方法 ,巧妙的绕过了确定窗宽的问题 ,能够结合模糊阈值法和该传统阈值法各自所能达到的优点 ,并且方法非常简单 ,明了 .实践证明 ,这种方法是行之有效的 ,并具有较强的场景适应能力 An improved fuzzy threshold selection method is proposed.According to the traditional starting point of fuzzy threshold method, which is not easy to determine the window width of membership function, combining the traditional easy threshold method, Fuzzy threshold method and the traditional threshold method can achieve their respective advantages, and the method is very simple and clear. Practice has proved that this method is effective and has strong scene adaptability
