abstract = "In this paper, we present the Hierarchy-of-Visual-Words (HoVW), a
novel trademark image retrieval (TIR) method that decomposes
images into simpler geometric shapes and defines a descriptor for
binary trademark image representation by encoding the hierarchical
arrangement of component shapes. The proposed hierarchical
organization of visual data stores each component shape as a
visual word. It is capable of representing the geometry of
individual elements and the topology of the trademark image,
making the descriptor robust against linear as well as to some
level of nonlinear transformation. Experiments show that HoVW
outperforms previous TIR methods on the MPEG-7 CE-1 and MPEG-7
CE-2 image databases.",
