Area of Science:

  • Computer Vision
  • Image Processing
  • Optimization Algorithms

Background:

  • Otsu thresholding is a common image segmentation method.
  • Standard Otsu method suffers from low segmentation accuracy and high time complexity with increasing thresholds.

Purpose of the Study:

  • To address the limitations of the standard Otsu threshold method.
  • To develop an efficient and accurate multi-threshold image segmentation technique.

Main Methods:

  • A novel enhanced double-mutation differential evolution algorithm with adaptive control parameters was developed.
  • The algorithm treats Otsu thresholding as an optimization problem, using maximum interclass variance as the objective function.
  • A twofold mutation approach and adaptive parameter search mechanism were employed.

Main Results:

  • The enhanced algorithm demonstrated robust performance in image segmentation.
  • Experimental results show superior accuracy and reduced time complexity compared to benchmark algorithms.
  • The method effectively determines optimal thresholds for multi-threshold image segmentation.

Conclusions:

  • The proposed enhanced double-mutation differential evolution offers a superior approach to Otsu threshold-based image segmentation.
  • This method provides a significant improvement in both segmentation accuracy and computational efficiency.
  • The algorithm is robust and performs well against existing methods.
