This paper discusses the relation between technical seeds in character recognition and market needs. The seeds can meet the market needs in condition that the seeds are at the level high enough. The character recognition techniques used so far, however, have not been matured but owed much to many constraints. In other words, human beings have made many artificial limitations to put premature OCR techniques into the practical use. The technical progress and competition are making these constraints unnecessary. In this context, the unconstrained OCR techniques will be explained.
