HYBRID SYSTEM FOR IDENTIFYING PRINTED PAGE |
摘要 |
A hybrid system for identifying a printed page. The system includes: (i) the printed page having human-readable content and a coding pattern printed in every interstitial space between portions of human-readable content, the coding pattern being either absent from the human-readable content or unreadable when superimposed with the human-readable content; and (ii) a handheld device for overlaying and contacting the printed page. The handheld device includes: a camera for capturing page fragment images; and a processor configured for: decoding the coding pattern and determining the page identity in the event that the coding pattern is visible in and decodable from the captured page fragment image; and otherwise initiating OCR or SIFT techniques to identify the page.
