| 摘 要： | 相关反馈方法是对基于内容图像检索系统的有效改进.对图像检索系统中基于向量转移的相关反馈算法进行了研究.针对传统向量转移算法速度较慢、误差较大的不足,提出了一种基于非查询向量转移相关反馈算法的改进办法,通过提高向量转移的速度和精度,有效的利用用户的反馈信息,从而加快相关向量的收敛速度.经过公用图像数据库上的实验测试表明,该方法能有效减少反馈次数,提高检索效率.

| Abstract: | Relevance feedback is an efficient improvement to the content-based image retrieval system.Relevance feed-back based on vector transfer in image retrieval is studied.Aimed at shortage of low speed and quite big error of vector transfer arithmetic,a new method of relevance feedback based on non-query vector transfer is presented.Increasing the speed and precision of vector-transfer can make use of feedback information efficiently and quicken convergence of relevant vector.The results of the experiments on th... |
