| 摘 要： | 在分析和研究快速细化算法和OPTA细化算法基础上,针对快速细化算法细化不彻底和OPTA算法模板设计的缺点提出了对OPTA细化算法的改进,设计了新的细化算法模板。经过实验证明改进的OPTA细化算法能够满足细化的基本要求,既保证了细化结果线条的单像素宽,又保持了原有图像线条的连通性,同时线条细节特征没有丢失,使细化结果得到了较大改善。

Improvement of the OPTA algorithm and its application in remote sensing images thinning |

| Abstract: | On the basis of analyzing and studying the quick thinning algorithm and the OPTA thinning algorithm,it is known that the thinning result of the quick thinning algorithm is not single pixel and the templates of the OPTA thinning algorithm is not optimized.So a method to overcome the shortcomings of the OPTA thinning algorithm is proposed and some thinning templates are redesigned.Through experiments,the new algorithm has been proved to fulfill the basic needs of the thinning algorithm,it guarantees that the width of the line is single pixel,maintains the connectedness of the original image.The effects of the new algorithm are evidently improved. |
