Gray-Level Histogram based Multilevel Threshold Selection with Bat Algorithm

Ultrasound image segmentation with multilevel threshold based on differential search algorithm

“…However, when the number of threshold increases, the exhaustive search strategy cannot obtain the thresholds quickly. Therefore, in recent years, researchers have tried to use search strategies, such as PSO [27], differential evaluation [28, 29], firefly algorithm [30], cuckoo search [31] and bat algorithm [32] to search for the optimal value of the objective function. In this paper, a new and efficient search algorithm, differential search (DS) algorithm, is taken into consideration [33].…”

A Soft-computing Assisted Tool to Detect and Analyse Brain Tumor

“…BA was anticipated by modelling the navigating and hunting potential of bats [12,16]. A detailed examination on the BA algorithm can be found in [14,15].…”

“…The heuristic approach based image processing is widely discussed due to its simplicity and lenience in implementation [12][13][14][15][16]. Kapur's entropy is one of the procedures, widely used because of its dominance and elasticity.…”

Medical Image Segmentation through Bat-Active Contour Algorithm

“…Echolocation involves emission of a very loud sound pulse and listens to the echo that returns from the objects [5]. Bat use this echo in formation to avoid obstacles and detect its prey [5]. Th is algorith m incorporates the advantages of the existing algorith m such as Particle Swarm Optimizat ion (PSO), Genetic Algorith m (GA), Firefly Algorith m (FA), Harmonic Search (HS) etc.…”
