Unsupervised Structure-Texture Separation Network for Oracle Character Recognition. (arXiv:2205.06549v1 [cs.CV])

Oracle bone script is the earliest-known Chinese writing system of the Shang
dynasty and is precious to archeology and philology. However, real-world
scanned oracle data are rare and few experts are available for annotation which
make the automatic recognition of scanned oracle characters become a
challenging task. Therefore, we aim to explore unsupervised domain adaptation
to transfer knowledge from handprinted oracle data, which are easy to acquire,
to scanned domain. We propose a structure-texture separation network (STSN),
which is an …
