Offline Chinese Handwriting Recognition : A Survey

Offline handwriting Chinese recognition (OHCR) is a typically difficult pattern recognition problem. Many authors have presented various approaches to recognizing different aspects of it. We present a survey and an assessment of relevant papers appearing in recent publications of relevant conferences and journals, including those appearing in ICDAR, SDIUT, IWFHR, ICPR, PAMI, PR, PRL, SPIEEDRR, and IJDAR. The methods are assessed in the sense that we document their technical approaches, strengths, and weaknesses, as well as the data sets on which they were reportedly tested and on which results were generated. We also identify a list of technology gaps with respect to Chinese handwriting recognition and identify technical approaches that show promise in these areas as well as identifying the leading researchers for the applicable topics, discussing difficulties associated with any given approach.
