| 摘 要： | 提出一种改进的遗传算法用于解决商标图像检索中的多特征权值分配问题.针对以往的传统分配方法所存在的不足,提出了利用改进的遗传算法来分配权值.主要方法是将遗传算法中的轮盘赌选择与最优解保存法结合,并将染色体基因重新排列后进行交叉.把遗传算法用于图像检索系统的多特征权值分配,并将得到的特征权值用于商标图像检索系统,目的是为了提高检索系统的效率和精度,而且通过这种方法得到的权值检索出来的结果也比较符合人的视觉感官.

| Abstract: | A revised genetic algorithm is proposed to solve the multiple-feature assignment in the trademark retrieval system.To overcome the deficiency in the traditional assignment,a revised genetic algorithm is proposed.The revised methods are the combination of Roulette wheel selection and the best solution conservation and the crossover of rearranged chromosomes.The new method is used in the trademark retrieval system and the efficiency and precision of the system is improved.The results also accord with the huma... |
