摘要
提出一种基于改进优势集聚类的无监督学习图像检索方法.使用有记忆的 SVM 相关反馈将底层视觉特征和高层语义相结合,并充分发掘图像之问的相似性以得到更接近用户检索要求的结果.实验结果表明,该方法能快速收敛于用户的查询概念,在图像检索系统的准确率和反馈次数方面表现出一定的优越性.
An unsupervised learning approach for content based image retrieval system is presented, which combines the low-level vision feature and the high-level semantics using the memorized SVM relevance feedback. The proposed approach fully explores the similarities among images in database by using the improved dominant set clustering to optimize the " relevance" feedback results from SVM. The experimental results show that the proposed method can be convergent to user's retrieval concept rapidly, and it has the superior precision and total relevance feedback times in image retrieval system.
