Abstract
A system and computer-implemented method for calibrating a document processing device from a composite document is disclosed. A composite document including human-readable content and machine-readable code marks is input into a document processing device. The machine-readable code marks are decoded to identify at least one spatial pointer including at least one nominal property of at least a portion of the human-readable content. The at least one nominal property is compared to an input property of the human-readable content. One or more distortions in the input property compared to the at least one nominal property are identified. The document processing device is calibrated based on the identified distortions.
Claims20
A system for calibrating a document processing device from a composite document, comprising:
- an input device to receive input of a composite document comprising an image human-readable content located in a foreground of the document and positioned relative to machine-readable code marks located in a background that are registered with the human-readable content and are encoded with at least one spatial pointer comprising a location identifier and supplementary information comprising at least one of human-readable characters, physical parameters, predefined information, and reference values for an ideal version of the human-readable content into a document processing device;
- a decoding module to decode the machine-readable code marks to determine the location identifier and the supplementary information, wherein the location identifier comprises spatial relationships of the relative positions between the foreground and the background for the ideal version of the human-readable content;
- a comparison module to compare the spatial relationships of the ideal version of the human-readable content with spatial relationships between the foreground and the background of the composite document and to identify distortions based on the comparison;
- and
- a calibration module to calibrate the document processing device based on the identified distortions.
A computer-implemented method for calibrating a document processing device from a composite document, comprising the steps of:
- inputting into a document processing device, a composite document comprising an image of human-readable content located in a foreground of the document and positioned relative to machine-readable code marks located in a background that are registered with the human-readable content and are encoded with at least one spatial pointer comprising a location identifier and supplementary information comprising at least one of human-readable characters, physical parameters, predefined information, and reference values for an ideal version of the human-readable content;
- decoding the machine-readable code to determine the location identifier and the supplementary information, wherein the location identifier comprises spatial relationships of the relative positions between the foreground and the background for the ideal version of the human-readable content;
- comparing the spatial relationships of the ideal version of the human-readable content with spatial relationships between the foreground and the background of the composite document and identifying distortions based on the comparison;
- and
- calibrating the document processing device based on the identified distortions,
- wherein the steps are performed on a suitably-programmed computer.
