Tesseract Ocr

1. INTRODUCTION 1.0 INTRODUCTION TO OCR Most of the schooling that is available in the companionship base is in printed median(a). This has hindered storing, exchanging and bear on of the information e1ectronically. Converting them into electronic medium is while consuming, 1abrious and expensive as well. These factors have motivated the great unwashed to explicate automated systems to transact this task.Optica1 Character Recognition, OCR, is the process of converting scanned depicts of work printed or hand-written school text into a computer processab1e format. The process of optica1 grapheme identification of any playscript can be broad1y tough pop out into five stratums: * Preprocessing * Segmentation * Feature extraction * Classification * Post-processing The preprocessing stage is a collection of operations that take successive transformations on an moving picture. It takes in a in the knock about image, reduces noise and distortion, removes skewness and performs skeltonizing of the image thereby simplifying the processing of the reside of the stages. The memberation takes place in a page image and separates the mutant logical parts, like text from graphics, lines of a paragraph, and characters of a word.

The characteristic extraction stage analyzes a text fragment and selects a trammel of features that can be used to unequivocally constitute the text segment. The selection of a stable and representative set of features is the heart of pattern acquaintance system soma. Among the different design issues involved in bui1ding an OCR system, mayhap the most consequential nonpareil is the se1ection of the type and set of features. The compartmentalization stage is the main(prenominal) decision do stage of an OCR system and uses the features extracted in he precedent stage to identify the text segment harmonise to the preset rules. The post-processing stage, which is the final exam stage, improves recognition by fine-tune the decisions interpreted by the previous stage and recognizes words by exploitation context.
