一种改进的遥感图像地标边缘匹配方法
Improved method of landmark edge matching for remote sensing image
摘要
Abstract
The distance transformation algorithm for edge matching is an effective landmark matching method. The disad-vantages of the traditional distance transformation algorithms are that searching processes is redundant, and the computation efficiency is poor. The new distance transformation algorithm, which cuts the redundant searching processes by adopting the steps of expanding edge-distance and setting approximate distance search threshold, is presented. Simulation results show that, the proposed algorithm is efficient for computation and has the same accuracy of matching as the traditional one.关键词
