- 摘 要:提出一种新的基于Pareto多目标进化免疫算法(PMEIA)。算法在每一代进化群体中选取最优非支配抗体保存到记忆细胞文档中 同时引入Parzen窗估计法计算记忆细胞的熵值,根据熵值对记忆细胞文档进行动更新,使算法向着理想Pareto最优边界搜索。此外,算法基于点在目标空间分况进行克隆选择,有利于得到分布较广的Pareto最优边界,且加快了收敛速度。与已有算法相比, PMEIA在收敛性、多样性,以及解的分布性方面都得到很好的提高。-Abstract:This paperproposed a

- 二维最大熵法和二维最小交叉熵法是目前常用的两种阈值分割方法, 但在某些时候因为两种方法获取的阈 值过高或者过低, 使得分割失效。针对此问题, 提出了基于二维最大熵法和二维最小交叉熵法结合的图像分割方法。 首先, 对二维最小交叉熵公式进行转化 然后, 利用多目标规划理论将这两种方法有机结合使得到的阈值既满足二维 最大熵原则, 又满足二维最小交叉熵原则 最后, 利用二维直方图的特点推导出新型递推算法搜索最佳阈值并降低计 算复杂度。-The thresho ld ing method
