Abstract: The library in our institute is the repository of all reports and design documents. In our library, reports belonging to the past three decades are preserved. The present day scans, reports are all searchable, but the scan reports that are two decades old are not searchable. They are very important and constantly referred by Scientists and Engineers for the fast breeder design purpose. It was decided all these documents would be scanned and added to the collection. When scanning was done, it was found a skew getting introduced into these documents and OCRs were not directly deskewing and required a pre-processing to be applied to the document. Optical character recognition (OCR) tool is a solution to extract the text from image and scanned documents. So it was decided an OCR would be developed using open source libraries and the de-skewing methods necessary would be added to make it useful to our task. This paper discusses what is an OCR, the different steps necessary to extract text from image files using an OCR, the OCR tool development, evaluation of the OCR tool and the de-skewing method implemented in the tool.
