Comparison between MPSO and MSFLA metaheuristics for MR brain image segmentation

Abstract

This paper presents a comparison study between two metaheuristics swarm intelligence (SI) techniques based Particle Swarm Optimization (PSO) and Shuffled Frog Leaping Algorithm (SFLA), to solve images segmentation problems. Performances in terms of Threshold values and run time execution of both Modified PSO (MPSO) and Modified SFLA (MSFLA) algorithms are reviewed and checked through MR brain medical images application that consist of partitioning an image into two regions, so get a binary image. MPSO and MSFLA are based on a new fitness function, which justifies their appointment.
