Abstract
According to principles of the invention, a method and apparatus are provided that organizes sample text into a format that facilitates character recognition. Sample text is analyzed for those features that define characters. Features that represent useful data for character recognition are stored and analyzed but features not useful for character recognition can be discarded. The sample text is segmented into arcs at each Y-extrema. A center of gravity is calculated for each arc. The arc features are saved as descriptive of the sample text for use in character recognition.
