Abstract:

Human skeleton model based on chain codes and curvature is 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.

Key words: chain codes, curvature, corner point, skeleton model
