Image processing apparatus and methods for pattern recognition |
摘要 |
Pattern detection methods, which may be embodied in copiers or scanners/printers, examine documents to be copied or printed to determine whether the documents contain one or more targeted patterns. The pattern detection methods include algorithms that look for certain features and geometric relationships between the features in determining whether one or more of the targeted patterns are present.
