A user interface tag for use in processing a document is provided. A printable surface is on one side of a document and an adhesive surface is on an other side of the document. The printable surface further includes a printed data field, including machine-readable marks of digital data encoding a service and a user identity; and a printed border surrounding the printed data field to define an iconic representation. A scanned representation of the machine-readable marks is decoded from the iconic representation to specify the user identity and the service.

User interface tag for use in processing a document

A user interface tag for use in processing a service on a scannable document is provided. A printable surface is on one side of the scannable document and an adhesive surface is on another side of the scannable document. The printable surface further includes a printed data field specified substantially within the printable surface, including machine-readable marks of digital data encoding a service code and a user identification number; and a printed rectilinear border surrounding the printed data field to define a rectilinear iconic representation. A scanned representation of the machine-readable marks is located by identifying the printed rectilinear border using corner candidates oriented in diametric opposition from among connected components identified on the document and the scanned representation of the machine-readable marks are decoded from the rectilinear iconic representation to specify the user identification number and the service code.

User interface tag for use in processing a service on a scannable document

A tag-based user interface scheme for digitizing and processing hardcopy documents utilizes a sticker that includes a printed data code representative of a user identity code and a service code. When the sticker is applied to a hardcopy document and scanned, the sticker is located, the data code is parsed, and a desired service is performed based upon the information stored in the data code.

User interface identification and service tags for a document processing system

A method for locating a substantially rectangular pattern, in any orientation, in a digitized image used in a document processing system operates by identifying all connected components within the image, discarding those that do not meet certain size criteria, and on the remaining connected components identifying eight compass-position extreme points, four of which may represent the corners of the rectangular pattern. The relationships among the extreme points are then analyzed to determine whether an expected diagonal length, expected height, and expected width of the pattern are all present within a selected tolerance.
