  • Each pixel is assigned a degree of membership to multiple regions.
  • The method demonstrates enhanced robustness in noisy image environments.
  • Achieved more accurate segmentation by avoiding hard pixel classifications.

Conclusions:

  • The proposed soft thresholding method offers a more resilient approach to image segmentation.
  • Fuzzy membership functions derived from histograms effectively handle noisy image data.
  • This technique provides a valuable alternative for image analysis in challenging conditions.
