Abstract:

To solve the problems of low segmentation accuracy, large calculation amount and slow segmentation speed in the traditional multi-threshold image segmentation methods, a multi-threshold image segmentation method based on improved sparrow search algorithm (ISSA) is proposed. First, the sparrow search algorithm (SSA) is optimized based on the flight behavior in the bird swarm algorithm (BSA), and four types of benchmark functions are used to evaluate the optimization performance of ISSA. Then, the between-class variance and Kapur entropy are used to perform the multi-threshold image segmentation, and the segmentation results of the two methods are compared. Finally, using PSNR, objective function value and standard deviation as evaluation criteria, ISSA is compared with the existing segmentation algorithms. The results show that ISSA has better search ability and development ability, and it has a significant improvement in terms of segmentation speed and accuracy.

Key words: image segmentation, improved sparrow search algorithm (ISSA), multi-threshold, Otsu, Kapur entropy
