This study introduces a new method for segmenting bone lesions in X-rays using texture analysis and topological maps. The technique improves lesion detection accuracy in medical imaging.

Area of Science:

  • Medical imaging
  • Image processing
  • Computational anatomy

Background:

  • Accurate segmentation of focal bone lesions in X-ray images is crucial for diagnosis.
  • Existing texture-based segmentation methods may lack precision.
  • Topological maps offer a novel approach to image analysis.

Purpose of the Study:

  • To introduce a texture-based segmentation technique for focal bone lesions in X-ray images.
  • To utilize topological maps for enhanced segmentation accuracy.
  • To evaluate the performance of the proposed method.

Main Methods:

  • Texture characteristics are defined using image-point correlation with feature vectors.
  • An improved labeling strategy is employed for topological map segmentation.

Related Experiment Videos

  • The method is tested on both original and synthetic X-ray images.

    • Main Results:

    • The developed technique demonstrates effective segmentation of focal bone lesions.
    • Quantitative quality measures confirm the method's performance.
    • Classifier-specific contribution analysis provides insights into feature importance.

    Conclusions:
