Abstract

Disclosed is an algorithm for hand-written yen sign recognition in the OCR system. This algorithm uses the characteristics of yen sign that it is the first character in the amount field.

This text was extracted from an ASCII text file.
This is the abbreviated version, containing approximately 62% of the total text.

Hand-Written Yen Sign Recognition Algorithm

      Disclosed is an algorithm for hand-written yen sign recognition
in the OCR system.  This algorithm uses the characteristics of yen
sign that it is the first character in the amount field.

      The OCR system has the several type of field to get the best
result.  For example, there are an address field, a mark field, a
stamp field and an amount field as field attribute.  In each field,
the various algorithm is applied respectively and the character
category is optimized.

      The amount field is the one of field type in the OCR system.
Only the yen sign, minus and numerals can be used in this field.
Especially the yen sign is the first character and does not appear in
the following position.  However the first character may be a numeral
or minus.  The minus is very easy to recognize for its simple shape.
But the hand-written yen sign has the various shapes and sizes.  So
the point of this algorithm is to distinguish between yen sign and
numerals.

      This algorithm uses the definition of the amount field and the
characteristics of yen sign that it is the first character in the
amount field.  These are very useful to implement following logic.

      For the first character in the amount field, the yen verifier-I
verifies the image and decides yen sign or not.  If result is TRUE,
this character is seemed to be yen sign.  If result is FALSE, the
numeral verifier verifies the image and decides...
