Method and apparatus for implementing spatial pointers and labeling via self-clocking glyph codes with absolute addressing for determination and calibration of spatial distortion and image properties

摘要

A method for printing a human-readable document from a composite image data file is disclosed. The method comprises obtaining a scanned image of the composite printed document to extract a spatial pattern of the document and other image property information. Next, the machine-readable content in the composite image is decoded to obtain reference information describing nominal spatial relationships of the human-readable and machine-readable content. The method then compares observed spatial relationships with reference spatial relationships to obtain a spatial deviation value. The spatial deviation value is then applied to the scanned image, and then a corrected image is outputted.
