| 摘 要： | 提出一种基于链码和曲率的人体骨架建模方法.先通过形态学方法得到人体骨架并将其简化后用邻域法求出骨架端点,然后用链码表示骨架遍历得到骨架分叉点,并通过上肢链码的曲率值得到骨架拐点,再对各个关键点进行相应的连接,建立人体骨架模型,进而表达人体上肢运动的有效信息.实验结果表明,该方法取得了较高的拐点检测准确率,且耗时较少,建模效果较好.

| Abstract: | Human skeleton model based on chain codes and curvatureis proposed. First morphology is used to extract human skeleton, which is simplified and whose endpoints are obtained via the neighbor points. The biforked points are gotten by tracking the skeleton which is demonstrated by chain codes. The corner point is obtained via the curvature from the chain codes of the upper limb. The human skeleton model is build up by connecting the relevant points in order to convey the effective information of the moving upper limb. Experiments show that the proposed method gains a high accuracy of searching corner points, and has a good modeling effect. |
