图像边缘检测所提出的广义模糊算子，从理论到方法的实现是任何其他传统的边缘检测技术的重大创\n新E它具有边缘定位精度高，检测速度快等优点E但该算法中参数的设置要凭经验选择，应用上不方便E笔者经过大量实验获取了有关参数计算的经验公式"使该方法中参数的自动设置成为可能。

General Fuzzy Operator(GFO)in edge detection proposed in[1] by Chen wufan is a great innovation in\nthe traditional theory and realized technique of image edge detection. It is superior to any classical edge detection in the higher precise location and the faster edge detection.However,some parameters in the the approach have to be empirically selected .which is not convenient in practice.An empirical equation is quation is given this paper based on experiments.Then,the parameters can be automatically and efficiently selected with this equation.
