| Abstract: | Edge detection is one of the main methods in the research field of digital image processing,in which the Laplace Gauss operator and Canny operator are introduced in this paper.The image processing function provided by the MatLab image processing tool box is employed to perform edge detection for image so that the relevant program and processing results are obtained.The result shows that the edge detection of Laplace Gauss operator and Canny operator is clear and has little noise. |
