摘要

景物边缘提取是图像理解的重要阶段

针对现有边缘提取方法存在的诸多问题

本文提出了一种独立边缘的自增强算法.此算法通过对边缘检测后图像的反复随机搜索获得各种可能的独立边缘轨迹

然后对所得的每条边缘进行独立自增强

最后根据积累增强的结果来提取边缘.通过大量的实验并与另外两种边缘提取的方法——启发式搜索法和松弛标记法进行了对比

表明我们的方法在提取边缘的同时有效地抑制了噪声

是一种很好的边缘提取方法.

Abstract

Edge extraction is an important stage to image understanding.To improve past methods for edge extraction

this paper presents an algorithm of accumulation of self-reinforcement of independent edges.First

use repetitive random searches to obtain various possible independent-edge trajectories in edge images.Then

self-reinforce and accumulate the search trajectories respectively.At last

extract the edges according to the results of the accumulation of self-reinforcement.Through lots of experiments and comparing with other techniques of edge extraction:relaxation algorithm and heuristic search algorithm

this method can extract edges effectively and suppress the noise significantly.
