摘　　要：提出了一种基于形态学和Canny算子的图像边缘提取算法。在经过预处理的基础上,运用形态学的开闭运算滤除噪声,局部灰度增强后用Canny算子检测得到清晰的连续的边缘。该算法对噪声有很好的鲁棒性,并得到真正的边缘。A new edge detection method based on morphology and Canny operator is developed.Using open and close operations to wipe off the noise after presolution, and enhancing the gray tevel partly, the clear and continuous edge can be got by Canny operator.This method has good robust to noise and can get the real edge.
