This study uses computer vision and texture analysis of X-ray images to identify diseased bone and lung tissues. The approach accurately distinguishes normal from pathological tissues, aiding in disease diagnosis.

Area of Science:

  • Medical imaging analysis
  • Computational pathology
  • Biomedical engineering

Background:

  • Fine-scale biological tissue structure is vital for disease diagnosis.
  • X-ray image textures, representing gray-level correlations, often indicate tissue abnormalities.
  • Accurate characterization of tissue structures in X-ray imaging is challenging.

Purpose of the Study:

  • To develop a Computer Vision approach for characterizing biological tissues in X-ray images.
  • To assess spatial gray-level dependence in bone and lung tissues using co-occurrence matrices.
  • To classify normal versus pathological tissues and differentiate between various pathologies.

Main Methods:

  • Utilized features derived from co-occurrence matrices to analyze spatial gray-level dependence.

  • Applied these texture features to standard X-ray images of bone tissue and lung parenchyma.
  • Employed a hybrid neural network for tissue classification tasks.

    • Main Results:

    • The computer vision approach successfully characterized spatial gray-level dependence in bone and lung tissues.
    • The hybrid neural network demonstrated capability in distinguishing pathological from normal tissues.
    • The system could effectively classify different types of pathologies within the analyzed tissues.

    Conclusions:

    • Computer vision techniques, particularly texture analysis via co-occurrence matrices, are effective for X-ray tissue characterization.
    • Hybrid neural networks provide a robust tool for automated diagnosis and classification of diseases from X-ray images.
    • This approach holds promise for improving the accuracy and efficiency of disease diagnosis in clinical settings.
