英文摘要：

In the process of image pre-processing,edge extraction is a very important step. Considering that current edge extraction algorithms cannot extract valid image edges,an improve method based on current edge extraction algorithm is proposed. The idea is to integrate some current algorithms and optimize some important parameters,then simulate the algorithm in the Matlab simulation platform. In this process,techniques such as Canny edge extraction,adaptive threshold segmentation and morphological filtering are used,and the processing of these methods are analyzed. The results show that the combination of these methods can effectively improve the quality of edge extraction.
