Improved COOT (ICOOT) Optimization

The ICOOT algorithm enhances the standard COOT with Lévy flights for exploration and quasi-opposition-based learning for exploitation. This dual approach overcomes stagnation, improves diversity, and balances the search process to find global optima more effectively in complex problems like image segmentation. The algorithm processes multiple steps including initialization, leader selection, objective function evaluation, and position updates, ensuring robust performance.

  • Enhanced exploration with Lévy flights
  • Improved exploitation via quasi-opposition-based learning
  • Better balance between exploration and exploitation
  • Avoids local optima stagnation
  • Faster convergence and higher accuracy

Multilevel Image Thresholding

Multilevel thresholding divides an image into several regions based on pixel intensity histogram values, addressing the heterogeneity of image intensities that bilevel thresholding cannot. This technique is critical for complex visual data, especially in biomedical imaging where differentiating healthy and cancerous tissues is vital.

  • Handles image heterogeneity effectively
  • Divides image into multiple distinct regions (classes)
  • Crucial for complex visual data (e.g., biomedical images)
  • Improved differentiation of tissues (e.g., healthy vs. cancerous)
  • More reliable results for real-world applications

Otsu's Entropy Maximization

Otsu's method maximizes the between-class variance to determine optimal threshold values, providing superior segmentation results. While effective, the original Otsu method can be suboptimal in the presence of image noise or high-dimensional search spaces. Integrating it with metaheuristic optimizers like ICOOT allows for more robust threshold selection, especially in multilevel scenarios.

  • Maximizes between-class variance for optimal thresholds
  • Effective for image segmentation
  • Unaffected by brightness and contrast variations
  • Computationally efficient for limited thresholds
  • Improved robustness when combined with metaheuristics

Lévy Flights Integration

Lévy flights are a type of random walk characterized by step lengths following a Lévy distribution, allowing for long-distance moves. In ICOOT, this mechanism enhances the exploration capability, reducing the likelihood of the algorithm getting trapped in local optima and increasing the diversity of generated solutions. It is crucial for effectively searching wide solution spaces.

  • Enhances exploration capability
  • Reduces algorithmic stagnation
  • Avoids local optima
  • Increases diversity of solutions
  • Allows for long-distance search moves

Quasi-Opposition-Based Learning (QOBL)

QOBL is an enhanced variant of Opposition-Based Learning (OBL) that generates a quasi-opposite solution (an alternative between the current and true opposite solution). This subtle modification strengthens the exploitation capability by increasing the possibility of locating optimal values near the global optimum, improving both convergence rate and solution accuracy more effectively than conventional OBL.

  • Strengthens exploitation capability
  • Accelerates convergence towards optimal solutions
  • Improves solution accuracy
  • Combines exploration and exploitation advantages
  • Better than conventional OBL for many optimization algorithms
