Character recognition

DETAILED DESCRIPTION We claim: 1.
A method for recognising a script written character comprising the steps of: entering the character using character enter means into a frame in a predetermined manner dependent on the character and producing a frame code indicative of at least one feature of the character, said frame code forming a topological feature; digitizing the character; storing the digitized character; extracting topological features of the character and including the frame code as one of the topological features; comparing the topological features of the character with the topological features of a plurality of reference characters defining a set of reference characters stored in a memory, each reference character of the set corresponding with a specific character; and performing a logic process to determine which reference character of the set of reference characters has topological features most closely corresponding to the topological features of the digitized character, thereby recognising the script written character.
