摘要
传统的边缘检测算子一般都只能得到比较宽的边缘,这为以后的图像处理带来了一定的困难。本文通过对图像边缘特征的分析,提出了一种新的边缘细化方法——P rew itt算子细化边缘。实验表明,这种方法能在保持原有信息的前提下,给出令人满意的细化结果。
The traditional image edge detection operators can only get very wide edges usually, which makes it difficult for the later image processing. In this article, we present a new edge thinning algorithm. By analyzing the image edge character, we find out that we can thin the edge by Prewitt operator. The experimental results show that the method not only can preserve the origin edge information, but also give us acceptable thin edges.
