摘　　要：遥感图像处理过程中,边缘提取一直是研究的热点与难点。通过介绍边缘的概念及种类,对传统的一阶微分方法和二阶微分方法进行了深入的探索,对各种微分方法的原理及过程,以及各种方法对图像的处理结果进行了对比分析,最后对遥感图像边缘提取方法所面临的问题和今后的发展方向表达了自己的观点。In remote sensing image processing, edge extraction is our focus and difficulty. The paper showed the conception and species of the edge,and deeply explored the differential operator methods of first order and differential operator methods of second order. We contrasting and analyzing the principles and processes of every differential algorithm and the conclusion of the image processing. In the end, we bring forward our viewpoint about the problems the remote sensing image edge extraction technology is facing and where is the developmental direction of it.
