Needs and seeds in character recognition

Discusses the relation between technical seeds in character recognition and market needs. The seeds can meet the market needs providing that the seeds are at a high enough level. The character recognition techniques used so far however, have not matured owing to many constraints. In other words, human beings have made many artificial limitations so as to put premature OCR techniques into practical use. The technical progress and competition are making these constraints unnecessary. In this context, unconstrained OCR techniques are explained
