An Improved African Vultures Algorithm for multi-threshold optimization in Chest X-Ray image Segmentation
This paper introduces IMMOAVOA, an Improved Multi-Objective African Vultures Optimization Algorithm, for multi-level threshold segmentation of chest X-ray images. It combines an average partial opposite learning strategy and an in-depth exploration mechanism with a novel multi-objective thresholding model integrating Otsu's method and 2D Kapur's entropy. Evaluated on ZDT, DTLZ functions, and chest X-ray images, IMMOAVOA demonstrates superior efficiency and segmentation quality over existing benchmark algorithms, offering more accurate region delineation for medical diagnostics.

Thresholding Objectives Combined
A new multi-objective thresholding model is developed, combining Otsu's method (maximizing between-class variance) with two-dimensional (2D) Kapur's entropy (maximizing information entropy). This synergistic approach enhances segmentation performance and reduces computational load compared to traditional single-objective methods.
Robust Chest X-Ray Segmentation
The proposed IMMOAVOA, integrated with the multi-objective thresholding model, substantially improves the quality of chest X-ray image segmentation across various threshold levels (2 to 10), as evidenced by superior PSNR, SSIM, and FSIM values compared to other multi-objective and single-objective algorithms.

Enterprise Process Flow
The IMMOAVOA algorithm workflow involves initialization, non-dominated sorting, selection of best vultures, calculation of satiety value, and then either exploration (with APOBL) or exploitation. An in-depth exploration strategy is applied at the end of each iteration to refine local exploitation, ensuring a balance between global search and local exploitation.

Computational Complexity
IMMOAVOA has a time complexity of O(T(NK+N^2)), where N is population size, T is iterations, and K is thresholds. This is significantly more efficient than traditional exhaustive multi-thresholding techniques like Otsu and 2D Kapur with O(L^K), making it scalable for high-dimensional tasks.
