METHOD OF IDENTIFYING PAGE FROM PLURALITY OF PAGE FRAGMENT IMAGES
摘要
A method of identifying a physical page containing printed text from a plurality of page fragment images captured by a camera. The method includes the steps of: placing a handheld electronic device in contact with a surface of the physical page; moving the device across the physical page and capturing the plurality of page fragment images at a plurality of different capture points; measuring a displacement or direction of movement; performing OCR on each captured page fragment image; creating a glyph group key for each page fragment image; looking up each created glyph group key in an inverted index of glyph group keys; comparing a displacement or direction between glyph group keys in the inverted index with a measured displacement or direction between the capture points for corresponding glyph group keys created using OCR; and identifying a page identity corresponding to the physical page using the comparison.
