C Ystem · Dalian Ligong Daxue xuebao · 2002
For the recognition of characters in electronic maps, this paper presents a skew correction algorithm, which can automatically get the angle of each character block with horizon and rectify it, if its written direction is not horizontal. The algorithm depends on one special characteristics of the Chinese character. Horizontal stroke and vertical stroke are the strokes most frenquently appearing in Chinese characters. The algorithm has been successfully used in GIS projects.
