An Efficient Adaptive Salp Swarm Algorithm Using Type II Fuzzy Entropy for Multilevel Thresholding Image Segmentation

Abstract

Salp swarm algorithm (SSA) is an innovative contribution to smart swarm algorithms and has shown its utility in a wide range of research domains. While it is an efficient algorithm, it is noted that SSA suffers from several issues, including weak exploitation, convergence, and unstable exploitation and exploration. To overcome these, an improved SSA called as adaptive salp swarm algorithm (ASSA) was proposed. Thresholding is among the most effective image segmentation methods in which the objective function is described in relation of threshold values and their position in the histogram. Only if one threshold is assumed, a segmented image of two groups is obtained. But on other side, several groups in the output image are generated with multilevel thresholds. The methods proposed by authors previously were traditional measures to identify objective functions. However, the basic challenge with thresholding methods is defining the threshold numbers that the individual must choose. In this paper, ASSA, along with type II fuzzy entropy, is proposed. The technique presented is examined in context with multilevel image thresholding, specifically with ASSA. For this reason, the proposed method is tested using various images simultaneously with histograms. For evaluating the performance efficiency of the proposed method, the results are compared, and robustness is tested with the efficiency of the proposed method to multilevel segmentation of image; numerous images are utilized arbitrarily from datasets.

Concentration of fecal coliforms in marine waters using satellite images in the vicinity of Pucusana. Bay, Peru.

“…The present study achieved the goal of estimating concentrations of fecal coliforms (dependent variable) in coastal areas using publicly available satellite data (independent variable) and comparing four well-known regression models. Future work to improve the estimation of fecal coliforms values can include implementing other image processing techniques such as intelligent optimization techniques with fuzzy entropy [27], salp swarm algorithms [28], signal processing techniques for enhanced feature selection and higher classification accuracy [29], Aquila optimizer and arithmetic optimization algorithms [30], etc.…”

Performance Enhancement in Clustering Cooperative Spectrum Sensing for Cognitive Radio Network Using Metaheuristic Algorithm

“…There are several meta-heuristic optimization algorithms developed that are inspired by nature. The efficiency of classification and prediction is improved by optimizing machine learning using the metaheuristic optimization algorithms [56][57][58][59][60]. Efforts have been made to improve SVM performance, but very few of these efforts have focused on SVM convergence.…”
