基于用户定义感兴趣区域的图像检索算法

IMAGE RETRIEVAL BASED ON USER DEFINED REGION-OF-INTEREST

提出一种利用用户定义感兴趣区域 (ROI)的图像检索方法 ,可以对多个感兴趣区域的相对位置加以约束以获得更高的查准率 ,相关反馈算法被用来进一步学习用户的检索意图。实验结果表明 ,该算法比现有图像检索方法具有更高的查准率。

An image retrieval algorithm, based on user defined Region-Of-Interest (ROI), is proposed. Spatial relation constraints of multiple ROIs, are deployed to gain improved accuracy. Furthermore, relevant feedback is used to gain better understanding of user′s intention. Experimental results show that this algorithm can achieve better accuracy than traditional ones.
