Published: March 23, 2023

The process of image segmentation is partitioning an into its constituent parts and a significant approach for extracting interesting features from images. Over couple decades, many efficient approaches have been formulated various applications. Still, it challenging complex issue, especially color segmentation. To moderate this difficulty, novel multilevel thresholding proposed in paper based on the electromagnetism optimization (EMO) technique with energy curve, named EMO curve (MTEMOE). compute optimized threshold values, Otsu's variance Kapur's entropy are deployed as fitness functions; both values should be maximized to locate optimal values. In methods, pixels classified different classes level selected histogram. Optimal levels give higher efficiency segmentation; used find thresholds research. methods image's histograms do not possess spatial contextual information finding levels. abolish deficiency instead histogram can establish relationship their neighbor pixels. study experimental results scheme, several benchmark images considered at compared other meta-heuristic algorithms: multi-verse optimization, whale algorithm, so on. investigational illustrated terms mean square error, peak signal-to-noise ratio, value reach, feature similarity, structural variation information, probability rand index. reveal that MTEMOE overtops state-of-the-art algorithms solve engineering problems fields.
