| Abstract: | 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. |
