Huang, Yonggang, Ma, Dianfu, Zhang, Jun and Zhao, Yongwang 2012, QDFA : query-dependent feature aggregation for medical image retrieval, IEICE transactions on information and systems, vol. E95-D, no. 1, pp. 275-279.
We propose a novel query-dependent feature aggregation (QDFA) method for medical image retrieval. The QDFA method can learn an optimal feature aggregation function for a multi-example query, which takes into account multiple features and multiple examples with different importance. The experiments demonstrate that the QDFA method outperforms three other feature aggregation methods.
