Abstract
The invention relates to optical character recognition and to apparatus for representing characters in a manner analogous to the field which one would expect to be induced on the retina of the eye by a particular character. A character to be recognized is compared with the same type of representation for prototypical characters and the determination made, using an elastic model, of the amount of deformation required to change the field of induction of the scanned character into the shape of that of the prototypical character. Character recognition is achieved by determining which prototypical character requires minimum energy to deform into that of the scan character or vice versa.
Claims4
A character recognizing apparatus, comprising:
- input means for inputting a character image;
- field of induction calculating means for calculating a field of induction on the retina of the character image input from said input means;
- and
- character recognizing means for recognizing a character based on difference between fields of induction on the retina of different character images calculated by said field of induction calculating means, by quantitatively evaluating a magnitude of a strain generated when the field of induction of one character image deforms to be matched with the field of induction of another character image.
