MULTIPLE IMAGE INPUT FOR OPTICAL CHARACTER RECOGNITION PROCESSING SYSTEMS AND METHODS
First Claim
1. A method of processing an image, comprising:
- receiving a digital version of the image;
processing the digital version of the image through at least two binarization processes to thereby create a first binarization and a second binarization;
processing the first binarization through a first optical character recognition process to thereby create a first OCR output file, wherein processing the first binarization through a first optical character recognition process comprises compiling first metrics associated with the first OCR output file;
processing the second binarization through the first optical character recognition process to thereby create a second OCR output file, wherein processing the second binarization through the first optical character recognition process comprises compiling second metrics associated with the second OCR output file; and
using the metrics, at least in part, to select a final OCR output file from among the OCR output files.

Abstract
A method of processing an image includes receiving a digital version of the image, processing the digital version of the image through at least two binarization processes to thereby create a first binarization and a second binarization, and processing the first binarization through a first optical character recognition process to thereby create a first OCR output file. Processing the first binarization through a first optical character recognition process includes compiling first metrics associated with the first OCR output file. The method also includes processing the second binarization through the first optical character recognition process to thereby create a second OCR output file. Processing the second binarization through the first optical character recognition process includes compiling second metrics associated with the second OCR output file. The method also includes using the metrics, at least in part, to select a final OCR output file from among the OCR output files.

8. A method of optically recognizing characters in an image, comprising:
-
creating multiple binarizations of the image using different binarization techniques; presenting each binarization to an optical character recognition (OCR) engine to produce OCR output file for each binarization; developing metrics relating to each OCR output file; and using the metrics, at least in part, to select a final OCR output file from among the OCR output files. - View Dependent Claims (9, 10, 11)

12. An optical character recognition system, comprising:
-
at least two binarization processes configured to convert grayscale images to bitonal images; at least one optical character recognition process configured to process bitonal images into final output files having characters therein; a metrics generation process configured to analyze output files and produce metrics associated therewith; a voting process configured to select a final output file from among the output files based on the metrics; a storage arrangement configured to store final output files and serve the information therein to users; and at least one processor programmed to execute the at least one optical character recognition processes, the at least one optical character recognition process, metrics generation process, and the voting process. - View Dependent Claims (13, 14)
