First Claim
1. A computer system for automatically recognizing a handwriting image and converting such image to text data including a sequence of validated words, comprising:
- an image input device for inputting as a data file the handwriting image that is to be converted to text data, anda computer, implementing under software control,a first handwriting recognition engine, responsive to said image input device, for analyzing said data file and providing one or more possible text words for each successive word in said data file, said first handwriting recognition engine further providing a resemblance indication for each possible text word indicating a level of resemblance between it and the handwritten word in the data file,a second handwriting recognition engine for analyzing words in said data file for which there is not a high level of confidence regarding the analysis performed by the first handwriting recognition engine, said second handwriting recognition engine providing one or more possible text words and a resemblance indication for each possible text word, anda control unit for selecting as a validated word the text word having the highest resemblance indication provided by the first handwriting recognition engine in the event that that text word has a high level of resemblance and a high level of confidence, and for selecting as a validated word the text word having the highest resemblance indication provided by the second handwriting recognition engine in the event that several text words have a high level of resemblance indication provided by the first handwriting recognition engine, and the text word having the highest resemblance indication provided by the second handwriting recognition engine is one of the several text words having a high level of resemblance indication provided by the first handwriting recognition engine.

Abstract
A system for automatically recognizing a handwriting image and converting such image to text data including a sequence of validated words, has an image input device, a number of handwriting recognition engines, and control unit. A first handwriting recognition engine is responsive to the image input device, for analyzing the data file and providing one or more possible text words for each successive word in the data file. The first handwriting recognition engine further provides a resemblance indication for each possible text word indicating a level of resemblance between its appearance and the appearance of the handwritten word in the data file. In the event that there is not a high level of confidence in the selection of the first handwriting recognition engine, a selection of a validated word is based on the selections of one or more of the other handwriting recognition engines.

8. A method of automatically recognizing a handwriting image and converting such image to text data including a sequence of validated words, comprising the steps of:
-
inputting a data file of a handwriting image that is to be converted to text data into a computer, analyzing said data file utilizing a first computer implemented handwriting recognition engine, and providing one or more possible text words for each successive word in said data file, and a resemblance indication for each of said possible text words indicating a level of resemblance between it and the handwritten word in the data file, analyzing words in said data file utilizing a second computer implemented handwriting recognition engine, where there is not a high level of confidence regarding the analysis performed by the first handwriting recognition engine, said second handwriting recognition engine providing one or more possible text words and a resemblance indication indicating a level of resemblance between it and the handwritten word in the data file, and using a computer, selecting as a validated word the text word having the highest resemblance indication provided by the first handwriting recognition engine in the event that that text word has a high level of resemblance and a high level of confidence, and using a computer, selecting as a validated word the text word having the highest resemblance indication provided by the second handwriting recognition engine in the event that several text words have a high level of resemblance indication provided by the first handwriting recognition engine, and the text word having the highest resemblance indication provided by the second handwriting recognition engine is one of the several text words having a high level of resemblance indication provided by the first handwriting recognition engine. - View Dependent Claims (9, 10, 11, 12, 13)
