| 摘要: |
| 传统的图像边缘检测算子一般都只能得到多像素宽边缘，这为后续的图像处理带来了一定困难。结合边缘走向趋势的估计技术以及对连通关键点判断的方法，提出了一种新型的边缘细化算法——保持连通的边缘细化算法。该算法能在保持边缘原有信息(连通和走向)的前提下，以较小的计算开销，给出理想的或是可接受的单像素宽细化结果。 |

| Abstract: |
| The traditional image edge detectors can only get multiple-pixel-wide edges usually, thus it is difficult to operate by post-processing methods. The paper presents a novel edge thinning algorithm named as connectivity preserved edge thinning algorithm, which combines the detecting strategy of the connectivity critical point with the estimating method of the edge direction. It can preserve the origin edge information such as connection and direction. Moreover, it gets ideal or acceptable single-pixel-wide edges with lower computing cost. |
