Including Foreground and Background Information in Maya Hieroglyph Representation

摘要

In the literature, all methods that represent Maya hieroglyphs compute local descriptors from the hieroglyph foreground. However, the background of a hieroglyph also contains information of its shape. Therefore, in this paper, we propose a new Maya hieroglyph representation that includes information from both, the foreground and the background. Our experimental results show that our proposal for representing Maya hieroglyphs allows obtaining better retrieval results than those previously reported in the state of the art.
