摘　　要：介绍了基于微分、形态学和小波变换等多种图像边缘检测的方法。在微分算子中分析了传统算子的特点和缺陷并讨论了几种具有良好边缘检测的算子。此外,还对新的边缘检测的理论和方法进行了介绍。This paper introduces image edge detection methods based on differential, math- ematical morphology and wavelet transform. In differential operators the character and limi- tation of traditional operators are analyzed and some good detection operators are discussed. In addition, this paper introduces new theory and method of edge detection.
