Devnagari Script Segmentation Based on JNI (Java Native Interface)

Abstract — Optical Character Recognition (OCR) is a form of computer vision that extracts alphanumeric characters from a digital image. The technology can be used for digitizing printed text, handwriting recognition, and making digital images searchable for text. Following the survey, an implementation of OCR Segmentation in JAVA will be presented and analyzed. OCR system converts scanned input document into editable text document. This paper presents the detailed description about the characteristics of Devnagari Script. How it is different from the other roman scripts. And what makes the Segmentation for any roman script different from the Segmentation for Devnagari script. The various stages of an OCR system are: upload a scanned image from the computer, segmentation process in which we extract the text zone from the image, recognition of the text and the last which is post processing process in which the output of the previous stage goes through the error detection and correction phase. This paper explains about the user interface provided with the OCR with the help of which a user can very easily add or modify the segmentation done by the OCR system.
