Abstract

The invention discloses a method for image processing based on an improved fireworks algorithm, and relates to the field of image processing. The method comprises the following steps: initializing the positions of N fireworks grains, and recording the fireworks grains as initial grains G(old); calculating the position Sj of explosion spark generated by explosion of each fireworks grain, the explosion radius Aj of each fireworks grain and the position of mutation spark; selecting gains G(new) participating in next iteration from all the grains; determining optimal grains with best fitness values in all the gains included in both the initial grains G(old) and the gains G(new), and optimizing the grains except the optimal grains in the optimal value direction according to a bacterial foraging operator; and taking N grains with highest fitness as initial grains G(old) for next iteration from the optimized grains until an optimal solution is obtained. The improved fireworks algorithm can better overcome the poor result of the traditional fireworks algorithm in classification and regression, and effectively improves the result of optimal value point search.

Description

technical field [0001] The invention relates to the field of image processing, in particular to an image processing method based on an improved fireworks algorithm. Background technique [0002] The swarm intelligence algorithm is simple in principle and has potential parallel and distributed characteristics. It solves complex problems through collaboration and is widely used in engineering fields such as image processing, robot control, unmanned traffic driving, social behavior prediction, communication network strengthening, and power system scheduling. widely used. Inspired by the phenomenon of fireworks explosions in the night sky, Tan Ying et al. proposed a new swarm intelligence algorithm——Fireworks Algorithm (FWA) in 2010. [0003] Fireworks algorithm has a self-adjusting mechanism of local search ability and global search ability, but a large number of experiments have proved that the solution results of Fireworks algorithm for functions whose optimal solution point...
