Appl. No.:

15/373790

International Classification:

G06K 7/10
G06K 19/06

Abstract:

A method of encoding indicia for one or more fields and subfields of a document is described. The one or more fields and subfields are encoded in extraction fields of the document with field descriptors. The field descriptors are unique at a parent level for the one or more fields and subfields, and provide information on relationships between the one or more fields and subfields. The field descriptors can include a current level of the field, a field's count identifier, a total number of fields at the current level, and an indication if the current level has subfields. The field descriptors can be encoded in the extraction field border via an embedded barcode.

Abstract:

A system of border detection on a document and for producing an image of the document is provided. In an exemplary embodiment, the system comprises: a frequency specific reflective border on the document; an image capture device; a filter tuned to the frequency of the reflective border; a border detection algorithm; and a processor communicatively linked to the image capture device, to the notch filter, and to the border detection algorithm. The image capture device is configured to capture an image of the document. The processor is configured to apply the filter to the captured image and to produce a second frame. The processor is further configured to apply the border detection algorithm to the second frame to determine a document border mask. The processor is further configured to apply the border mask to the captured image to produce a document image.
