TECHNIQUES FOR DETECTING USER-ENTERED CHECK MARKS
First Claim
Patent Images
1. A method of using a mobile processing apparatus to process check marks in a document having pre-formatted fields for entering the check marks, the method comprising:
- using a digital camera associated with the apparatus to produce a first electronic file containing a 2D digitized image of the document; and
using the apparatus for;
(a) in the first file, detecting identifiers of the document and markers identifying location and orientation of portions containing the pre-formatted fields;
(b) producing a second file wherein the 2D digitized image is modified to match a digital template of the document;
(c) using the digital template for electronically extracting digitized images of the pre-formatted fields from the second file; and
(d) detecting presence of the check marks in the digitized images of the pre-formatted fields based on analysis therein of non-background pixels.

Abstract
A digital camera associated with a mobile processing apparatus is used to produce a file containing a 2D digitized image of a document having pre-formatted fields for user'"'"'s check marks. The image is electronically matched to a digital template of the document for extracting digitized images of the pre-formatted fields, which are thereafter analyzed for presence therein of user-entered check marks.

12. A platform for processing check marks in a document having pre-formatted fields for entering the check marks, the platform comprising:
-
a mobile processing apparatus associated with a digital camera adapted to produce a first file containing a 2D digitized image of the document; and a local processor provided with hardware or software resources configured to perform; (a) in the first file, detecting identifiers of the document and markers identifying location and orientation of portions containing the pre-formatted fields; (b) producing a second file wherein the 2D digitized image is modified to match a digital template of the document; (c) using the digital template for electronically extracting digitized images of the pre-formatted fields from the second file; and (d) detecting presence of the check marks in the digitized images of the pre-formatted fields based on analysis therein of non-background pixels. - View Dependent Claims (13, 14, 15, 16)

17. A medium storing processor-readable instructions for processing check marks in a document having pre-formatted fields for entering the check marks, the instructions which, responsive to execution in a mobile processing apparatus associated with a digital camera, cause the apparatus to perform:
-
using the camera to produce a first file containing a 2D digitized image of the document; and selectively using the apparatus for; (a) in the first file, detecting identifiers of the document and markers identifying location and orientation of portions containing the pre-formatted fields; (b) producing a second file wherein the 2D digitized image is modified to match a digital template of the document; (c) using the digital template for electronically extracting digitized images of the pre-formatted fields from the second file; and (d) detecting presence of the check marks in the digitized images of the pre-formatted fields based on analysis therein of non-background pixels. - View Dependent Claims (18, 19, 20, 21, 22)
