Symbiotic Organisms Search Algorithm for multilevel thresholding of images

作者:

Highlights:

• Optimal thresholds selection for images was performed by SOS optimization algorithm.

• Six different algorithms were used with Otsu's and Kapur's fitness functions.

• Results were analyzed with fitnesses, PSNR, SSIM, CPU time, standard deviation,Friedman test.

• It has been observed that Kapur based SOS algorithm is successful in many cases.

• GWO algorithm has the shortest execution time among all proposed algorithms.
