This study presents a novel skeleton pruning method using contour partitioning, specifically Discrete Curve Evolution (DCE). The technique produces stable, perceptually accurate skeletons without spurious branches or point displacement, outperforming existing methods.

Area of Science:

  • Computer Vision
  • Image Processing
  • Computational Geometry

Background:

  • Skeleton pruning is crucial for shape analysis and representation.
  • Existing methods often introduce artifacts like spurious branches or displace skeleton points, affecting accuracy and perceptual relevance.

Purpose of the Study:

  • Introduce a novel skeleton pruning method based on contour partitioning.
  • Address limitations of existing methods, focusing on stability, perceptual accuracy, and topological correctness.

Main Methods:

  • Skeleton pruning via contour partitioning.
  • Utilizing Discrete Curve Evolution (DCE) for optimal contour partitioning.
  • Theoretical analysis and experimental validation.

Main Results:

  • The proposed method yields skeletons that align with human visual perception.
  • Skeletons demonstrate high stability against noise and shape variations.
  • Guaranteed absence of spurious branches and no displacement of skeleton points, preserving maximal disk centers.

Conclusions:

  • The contour partitioning-based skeleton pruning method offers significant advantages over existing techniques.
  • The approach ensures topologically consistent, stable, and perceptually accurate skeletons.
  • Preservation of skeleton point properties (e.g., maximal disk centers) enhances shape representation fidelity.
