Adaptive Online Handwritten Character Recognition Using Multi-Stage Discriminators

       Disclosed is a method for adapting users' writing styles
in online handwritten character recognition by using multi-stage
discriminators.

      The disclosed method provides a recognizer consisting of two
(or more) different discriminators, which process the handwritten
character data as follows:
 (1) When a user writes a character, the first (or top) discriminator
starts to recognize the handwritten data.
 (2) If the user cannot find his/her written character in the
resulting candidates, then he/she can initiate the second (or
subsequent) discriminator to re-recognize the same handwritten data.
      Consequently, he/she need not write the character again.
 (3) If the user frequently initiates the second (or subsequent)
discriminator, it automatically becomes the first (or top)
discriminator, in order to conform to his/her writing style.

      An effective way of multi-staging discriminators is to assign a
high-speed one that does not require much processing for the first
stage, and a high-recognition-rate one that supports stroke
connections requiring intensive processing for the second stage.

      Existing methods also support stroke connections in order to
give a high recognition rate. However, for users who write in
unjoined letters (unjoined writers), this support is not necessary
and only decreases the speed. On the other hand, for users who write
cu...
