Method and system for character recognition
First Claim
Patent Images
1. A method in a computing system for identifying a sequence of glyphs, the method comprising:
- receiving an image of a sequence of glyphs;
for each of a subset of glyphs of the sequence;
determining whether the glyph matches a retained glyph;
when the glyph matches a retained glyph, assigning to the glyph a character identity associated with the retained glyph;
when the glyph does not match a retained glyph;
retaining the glyph;
selecting a character identity for the unmatched glyph; and
assigning the selected character identity to the unmatched glyph;
generating a representation of the image of the sequence of glyphs with the assigned character identities; and
identifying the sequence of glyphs using the generated representation.

Abstract
Character recognition is described. In one embodiment, it may use matched sequences rather than character shape to determine a computer-legible result.

6. A system for identifying a text sequence within an image, the system comprising:
-
an image reception component, wherein the image reception component is programmed to receive an image of a text sequence, the text sequence including multiple glyphs unknown to the system; a glyph image component, wherein the glyph image component is programmed to associate an identity to a subset of the multiple glyphs based on (1) similarities in shape between the glyphs within the image of the text sequence, and (2) relative locations of the glyphs within the image of the text sequence; and a text representation component, wherein the text representation component is programmed to generate a text representation by replacing the glyphs with the associated identities. - View Dependent Claims (7, 8, 9)
