| 英文摘要 | It is difficult for existed polygon medial axis (MA) extracting methods to address complex polygon and to make sure of the accuracy and connectivity of MA. A new curved-polygon MA extracting method is introduced. Firstly, concepts of curved-polygon together with its MA are given. Secondly, the mean distance transformation (MDT) of the nearest border point set (NBPS) is put forward. Thirdly, a new MA point judgment regulations is constructed, and the method of greed points-growth and detection are used to extract MA. Fourthly, various complex polygons were used to inspect this new method. It was found that the impacts of border noisy points are eliminated effectively and both the accuracy and connectivity of MA are satisfactory which overcome the shortcomings of traditional methods. |
