The traditional edge detection methods (Roberts, Sobel, Prewitt, log, canny) are introduced, In view of the defects of traditional Canny algorithm, an improved Canny algorithm based on adaptive smoothing filter and 3 * 3 domain gradient amplitude calculation method is proposed for edge detection. The experimental image is obtained by using MATLAB, and the comparison of each operator algorithm without noise is carried out. The comparison of each algorithm with noise shows that the original Canny operator and the improved Canny operator are better than each other without noise
