| Abstract: | Gauss-Laplace（LoG） operator uses Gaussian smoothing filter.Gaussian filter controls the cut-off frequency to change the effect of filtering.This paper mainly analyzes the characteristics of the Gaussian low-pass filter and LoG operator,and the effect of LoG operator edge detection is analyzed by computer simulation in noisy image filtering. |

| Keywords: | LoG operator cut-off frequency gaussian noise |
