Application ID: 13864180

Base Claim:
1. A computer-implemented method of assessing quality of computer-generated text in a document image, the method comprising: identifying text quality scores associated with a plurality of digital text characters generated from the document image, a text quality score for a target character describing a likelihood of the target character being at a location of the target character within the document image; identifying a plurality of subsets of characters having associated text quality scores that differ from text quality scores associated with neighboring characters in the document image by more than a threshold value; segmenting the document image into a plurality of segments associated with different text quality scores responsive to the identified plurality of subsets of characters; determining a representative text quality score for each segment of the document image; and storing the representative text quality scores in association with the segments.

Claim 4:
4. The method of claim 1 , wherein identifying a subset of characters having associated text quality scores that differ from text quality scores associated with neighboring characters in the image comprises: combining the text quality scores of the characters in the identified subset to produce a combined text quality score representing the identified subset of characters; and wherein the segmenting segments the document image responsive to the combined text quality score.
