Comparing Tesseract results with and without Character localization for Smartphone application
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2013, Vol 2, Issue 5
Abstract
Tesseract is considered the most accurate free OCR engine in existence. Android operating system based Smartphones application where images taken from camera of mobile device or browsed from gallery are preprocessed. The text of these images will be accurately localized within the device using special localization method. Localized text sub-image will be fed for text extraction to the best OCR engine called “Tesseract”. In this paper, Tesseract results with and without Character localization is compared based on computation time in milliseconds. Each image is taken 10 times and time for each is calculated. The computation time is taken as average of this 10 values. There is drastic change in time and accuracy of localized image compared to nonlocalized image. Finally we concluded the importance of localization in OCR system especially for Smartphone application where we OCR a few words and need high accuracy.
