Stroke-based intelligent character recognition using a deterministic finite automaton

Development of an information retrieval tool for biomedical patents

“…OCR is a computer science technology that associates the image of a character to its symbolic identity. OCR uses an offline approach to character recognition, in which the recognition is done after the completion of writing or printing and not done when characters are being drawn [28] . Since OCR systems are based on patterns (numbers, letters or punctuation characters), the first step is to "teach" the machine about these patterns.…”
