Abstract :
Introduction: A Document is any sort of object that conveys relevant information. This wide definition of document goes far beyond paper documents, the most usual form of document, and encompasses all sorts of materials from bones of pre-historical animals to videos, etc. Document Engineering is the area of knowledge focused in principles, algorithms, tools and processes that allow creating, managing, store, compact, access, and maintaining digital documents. The World Wide Web (WWW) made the fields of document recognition and retrieval grow rapidly in recent years. New application areas such as the, digital libraries, and video- and camera-based OCR have appeared lately.
