Abstract

The method involves entering and digitising the character. The digitised character is then stored in memory. Codes representing topological features of the character are extracted form the character. The topological features are compared with a set of reference topological features stored in a memory. Each of the set of reference character correspond 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 digitised character thereby identifying the script written character.
