摘要: 针对基于内容的图像检索难于通用化的问题,使用MPEG-7的颜色布局描述符和平行纹理描述符建立联合特征空间,并采用遗传算法对其内部特征权重以及描述符之间的权重进行优化。实验结果表明,使用上述方法大大降低了系统检索时间,明显提高检索效率。

Abstract: Aiming at the difficulty of making the content based image retrieval to be universal,the color layout description and homogeneous texture description of MPEG-7 are used to establish the combined feature space.This paper uses the genetic algorithm to optimize both the inner feature weight within the description and the outer weight between the descriptions.The experiment result shows that the retrieval time decreases and the efficiency increases.
