| description | This invention relates to a method and apparatus for recognizing a script written character. The character is entered using character entering means and digitised by appropriate means. The digitised character is then stored in, for example, a memory. Codes representing topological vector features of the character are extracted from the character, then the topological and vector features of the character are compared with a set of reference topological and vector features stored in a memory. Each of the set of reference characters corresponding with a specific script written character. A logic process is then performed to determine which of the set of reference features most closely corresponds to the topological features of the digitized character thereby identifying the script written character. The relative weighting of the topological effect and the vector effect can be varied for different types of script to enable still more accurate recognition. |
