Character recognition

The method of claim 3, wherein the microfeature code is given by:

• ##EQU6## where Rik (k=1, . . . 5, i=1 . . . 15) is the microfeature code of the input character,
• Rjik (k=1, . . . 5, i=1 . . . 15) is the microfeature code of the j-th reference character,
• P is the number of non-zero Rik elements,
• Pj is the number of non-zero Rjik elements,
• and M is the following matrix:
• {0. 0,0,0,0,0,0,0}
• {0,3,0,2,1,2,0,1}
• {0,0,3,2,1,0,2,1}
• {0,2,2,3,0,1,1,2}
• {0,1,1,0,3,2,2,0}
• {0,2,0,1,2,3,1,1}
• {0,0,2,1,2,1,3,1}
• {0,1,1,2,0,1,1,3}.

Apparatus for recognizing a script written character comprising:

• character enter means for entering and receiving the character;
• digitizing means for digitizing the character;
• storage means for storing the digitized features;
• feature extracting means for extracting topological features;
• vector features microfeatures and dimension features representative of said character;
• comparing means for comparing the extracted features of the character with a set of reference features stored in a memory, each of the set corresponding to a specific character;
• and
• logic means for identifying which of the set of reference features most closely corresponds to the features of the digitized character, thereby recognizing script written character.
