摘　　要：提出了动态阈值Prewitt算子的边缘提取模板;研究了模板动态阈值取值及其用十字模板对边缘细化的算法,实验表明此算法能够弥补经典Prewitt算子边缘检测的不足,同时该算法对图像的边缘细化效果很好。Proposed a kind of edge detection template of dynamic threshold Prewitt operator; Has studied the template dynamic threshold algorithm and edge thinning operator with the crossed template, the experiments show that this algorithm could make up the classical Prewitt operator＇ s insufficiency, simultaneously this algorithm was very good to the image edge thinning effect.
