| Abstract |
The ultimate dream in pattern recognition
is to achieve a 100% recognition rate.
However, it is not so easy.
In this report, for achieving a 100% recognition rate with a 0%
rejection rate, we propose a new framework that the discriminator
receives not only a pattern itself but also supplementary information
that assists recognition.
We clarify the relationships among
a recognition rate, a rejection rate and quantity of supplementary
information.
For printed characters, experiments showed that
4 bits were required in the leave-one-out (L) method
and 1 bit was in the resubstitution (R) method
to achieve a 100% recognition rate with a 0% rejection rate.
Furthermore,
compared with identification codes such as a character code,
the proposed approach compresses about
1/12 in quantity of supplementary information, and
about 1/9 in size of area of QR code.
Thus, the proposed framework combines advantages of
the conventional approach of pattern recognition and an identification
code. |
