为了在实际应用中能够选择最佳的边缘检测方法，采用Matlab语言鳊程，将若干常用的边缘检测方法应用于花瓶边缘检测仿真实验．包括微分算子法(Robert算亍、Sobel算予、Prewitt算子和Kirseh算子)、高斯一拉普拉斯算子法、坎尼算子法、零交叉法和Frei—chen边缘检测法等,并进行了对比分析。-In practice, in order to be able to　the best edge detection method using Matlab language bream drive to several commonly used edge detection method is applied to edge detection simulation vase. Including differential operator method (Robert count right foot, Sobel operator I, Prewitt operator and Kirseh operator), Gauss-Laplace law, Canny operator, zero crossing method and Frei-chen edge detection method and make a comparative analysis.
