Ascertain Error and Accuracy in Optical Character Recognition Nov 2012 – April 2013

Role: - Java Research Developer

Responsibilities:

Developed a User interface which provides the percentage of accuracy and level of confidence for matching correct letters in a given word.

The objective of the project is to choose an appropriate Optical Character Recognition (OCR) engine based on key deciding factors like OCR speed.

Extract information from OCR output which would allow us to extract and index only correct information and to post-process specific parts of the OCR output with targeted resources.

This application provides whole image and word level confidence values along with the output digital text.

The user can interpret the accuracy of the OCR engine and can be further used to classify whether a word is recognized or not based on threshold value.

Environment: Windows, Visual Studio, Java, JSP, Servlets, Eclipse.
