Web3.2 Hierarchical Matching Pursuit KSVD is used to learn codebooks in three layers where the data matrix Y in the ﬁrst layer consists of raw patches sampled from images, and Y in the second and third layers are sparse codes pooled from the lower layers. With the learned codebooks D, hierarchical matching pursuit builds a fea- 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.
