This study introduces a new method for content-based medical image retrieval using Haar wavelet transform for texture analysis. Experiments show this approach significantly outperforms retrieval methods based on co-occurrence matrices.

Area of Science:

  • Medical imaging
  • Computer vision
  • Signal processing

Context:

  • The exponential growth of digital medical image archives necessitates efficient retrieval systems.
  • Content-based image retrieval (CBIR) is crucial for managing and accessing large medical image databases.

Purpose:

  • To develop and evaluate a novel medical image retrieval method utilizing Haar wavelet transform for texture analysis.
  • To compare the efficacy of the proposed Haar wavelet transform method against traditional co-occurrence matrix-based retrieval techniques.

Summary:

  • A novel content-based medical image retrieval system is presented, employing Haar wavelet transform for detailed texture analysis.
  • The system's performance was experimentally validated against a co-occurrence matrix approach, demonstrating superior retrieval accuracy.
