摘要
为了提高彩色图像的分割效果,提出一种基于改进的萤火虫优化(IGSO)算法的彩色图像多阈值分割方法,该方法以Kapur熵为目标函数。针对基本萤火虫优化(GSO)算法进化后期收敛速度慢和求解精度低的问题,采用自适应步长和添加全局信息两种策略,提出了一种改进的萤火虫优化(IGSO)算法。IGSO算法根据步长和萤火虫的移动方向对萤火虫算法收敛性的影响,在萤火虫移动过程中引入全局信息,采用随着迭代次数和搜索空间维数自适应变化步长的策略,来提高收敛性能。实验结果表明,该方法能够较好地对彩色图像进行分割,其性能优于基本的萤火虫优化(GSO)算法、改进的量子行为粒子群优化算法(CQPSO)和改进的细菌觅食算法(MBF)。
