A Preprocessing Algorithm for Tibetan Character Recognition
Deng Gangyi · Jisuanji gongcheng · 2001
The preprocessing is an important part of the character recognition system. Its performance will seriously affect the capacity of the system. In this paper, we present a preprocessing algorithm for Tibetan character based on the topology structures and writing habits of Tibetan characters. The entire preprocessing procedure includes binary, page analysis, skew correction, character segmentation and normalization. In addition, some basic features of Tibetan characters are extracted. These features can be used for recognition and postprocessing.
