Webplored. The success of hierarchical matching pursuit (HMP) algorithm in classification [16] motivates us to employ the hierarchical sparse coding architecture in image retrieval to explore multi-scale cues. A global feature using HMP is introduced in this paper for image retrieval, which has not been considered in this field to our knowledge. Webproceedings.neurips.cc
