The Using of Differential Algorithm in Remote Sensing Image Edge Extraction
遥感图像边缘提取微分方法及其应用

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 an...
