This study introduces a genetic algorithm (GA) for automated detection and classification of microcalcification clusters in mammograms. The GA method achieves high performance, improving early breast cancer detection accuracy.

Area of Science:

  • Medical imaging analysis
  • Artificial intelligence in healthcare
  • Biomedical signal processing

Background:

  • Early detection of breast cancer is crucial for improving patient outcomes.
  • Microcalcification clusters are key indicators of breast cancer in mammograms.
  • Automated analysis of mammograms can aid radiologists in diagnosis.

Purpose of the Study:

  • To develop and evaluate a genetic algorithm (GA) for automated classification and detection of microcalcification clusters.
  • To enhance the accuracy and efficiency of microcalcification detection in digital mammograms.
  • To benchmark the proposed GA technique against existing methods.

Main Methods:

  • Image transformation into a feature domain using pixel mean and standard deviation within a 9x9 window.
