Implementation of OCR  The ability to recognize characters and text from images has been investigated for a number of years  Implementation issues  Why to use Tesseract library for OCR? [3]  Expected difficulties  lighting, font type, reflective surfaces, and motion.  Refernc 3.

Project Goals  Identify challenges to implement the application  Implementation of OCR for mobile device  Determine the usability of a live system  Identify benefits of the application  Explore possible use of local database to get license information  Extensibility of the system through the use of remote data stores
