Area of Science:

  • Medical Imaging
  • Computational Biology
  • Image Analysis

Background:

  • Accurate segmentation of cervical cell cytoplasm is crucial for disease diagnosis.
  • Existing methods struggle with non-bimodal image histograms and non-ideal imaging conditions.

Purpose of the Study:

  • To propose and evaluate a robust cytoplasm segmentation method for cervical cell images.
  • To improve segmentation accuracy, especially under challenging imaging conditions.

Main Methods:

  • Utilized the A* channel in CIE LAB color space for contrast enhancement.
  • Applied Otsu multiple thresholding for initial segmentation of images with non-bimodal histograms.
  • Refined initial segments using a multi-way graph cut algorithm.

Main Results:

  • The proposed method achieved 93% accuracy in cytoplasm segmentation.
  • Demonstrated superior performance compared to state-of-the-art methods on 21 cervical cell images.
  • Effectively handled non-ideal imaging conditions and complex histogram distributions.

Conclusions:

  • The graph cut-based method offers a highly accurate and robust solution for cervical cell cytoplasm segmentation.
  • This approach shows significant potential for improving automated analysis in cytopathology.
