Area of Science:

  • Medical Image Analysis
  • Computer Vision
  • Artificial Intelligence

Background:

  • Fuzzy C-Means (FCM) is a popular clustering algorithm for medical image segmentation.
  • Standard FCM is sensitive to noise and does not effectively utilize spatial information.
  • Noise and lack of spatial consideration limit the accuracy of traditional FCM in medical imaging.

Purpose of the Study:

  • To develop an improved FCM algorithm for medical image segmentation.
  • To enhance the robustness of FCM against noise by integrating spatial features.
  • To improve the accuracy and reliability of medical image segmentation using an enhanced FCM approach.

Main Methods:

  • A novel medium mathematics system was developed to process fuzzy information.
  • A medium similarity measure based on the measure of medium truth degree (MMTD) was established.
  • A new medium membership function was defined using pixel-neighbor correlation, incorporating spatial information into FCM.

Main Results:

  • The proposed MMTD-based FCM algorithm demonstrated superior anti-noise capabilities compared to standard FCM.
  • The improved algorithm achieved segmentation with greater certainty and reduced fuzziness.
  • Experimental results validated the effectiveness of the enhanced FCM in handling noisy medical images.

Conclusions:

  • The MMTD-based improved FCM algorithm offers enhanced performance for medical image segmentation.
  • The incorporation of spatial information significantly improves noise resistance and segmentation accuracy.
  • This method presents a practical and effective solution for noise-robust medical image segmentation.
