| 摘 要： | 为实现彩色图像噪声的滤波,基于遗传算法技术构建了一种新型的彩色图像滤波器,在彩色图像的矢量中值滤波过程中,该滤波器利用遗传算法具有寻找全局最优解的能力,获得滤波器窗口的最优权值。从滤波效果看,有一定提高,并进一步提出了一种基于个体相似性的遗传算法:当种群的多样性较好时,采用标准的交叉策略;当种群的多样性较差时,根据个体的相似性选择个体配对,避免相同的个体配对交叉,减少高度相似个体进行配对交叉的概率,从而提高交叉操作的效率。

| Abstract: | In order to filter the impulse noise in the color image or picture,this article proposes a new weighted vector directional filter based on the GA(Genetic Algorithm).This filter obtains the ability to get globally optimal weight value using GA.There are much enhancement applications in color image filtering.This paper further proposes an improved genetic algorithm based on the similarity of chromosomes,standard crossover operation is used when the diversity of population is good;otherwise,chromosomes are matched based on their similarity,crossover between two same chromosomes are avoided,and the matching probability of two highly relevant chromosomes is decreased,the efficiency of crossover operation is improved.The simulation result shows that this improved algorithm is effective. |
