ABSTRACT:
Encoded data embedded in an iconic, or reduced size, version of an original text image is decoded and used in a variety of document image management applications to provide input to, or to control the functionality of, an application. The iconic image may be printed in a suitable place (e.g., the margin or other background region) in the original text image so that a text image so annotated will then always carry the embedded data in subsequent copies made from the annotated original. The iconic image may also be used as part of a graphical user interface as a surrogate for the original text image. An encoding operation encodes the data unobtrusively in the form of rectangular blocks that have a foreground color and size dimensions proportional to the iconic image so that when placed in the iconic image in horizontal lines, the blocks appear to a viewer to be representative of the text portion of the original image that they replace. Several embodiments are illustrated, including using the iconic image as a document surrogate for the original text image for data base retrieval operations. The iconic image may also be used in conjunction with the original text image for purposes of authenticating the original document using a digital signature encoded in the iconic image, or for purposes of controlling the authorized distribution of the document. The iconic image may also carry data about the original image that may be used to enhance the performance and accuracy of a subsequent character recognition operation.
