摘要 介绍了Canny算子的基本原理和计算实现,给出Canny边缘检测算法的实现步骤.利用MATLAB进行仿真,通过与其他边缘检测算子的比较,实验结果证明Canny算子对噪声抑制较好,定位准确.最后与数学形态学相结合,将其运用到阀门气密性测试中,获得良好效果. The theory and realization of canny operator is introduced and the process of the operator＇s realization is also given. Through MATLAB simulation and comparison with other edge detection operators, the experimental results indicate good SNR （signal-to-noise） and accurate position setting of canny operator. Finally, combined with mathematical morphology, canny edge detection is used in valve tests with good result.
