Abstract

A system for evaluating a user-marked document having a response area and at least one image marker, the system including an image capturing device to obtain a digital image of the user-marked document, and a computer to identify positional information of the at least one image marker from the obtained digital image of the user-marked document, wherein the image marker provides context to marks on the user-marked document based on the position of the mark relative to the image marker.

Abstract

A method and system for processing a handwritten response on a user-marked document having a response area and at least one image marker which includes a means for capturing a digital image of the user-marked response sheet and a computer having programming to perform steps including identifying spatial position information of the at least one image marker in the captured digital image, calculating position information of the response area in the captured digital image relative to the identified spatial position information of the at least one image marker, and identifying pixel-value data of the response area after the user creates marks on the user-marked response sheet.

Abstract

A system for evaluating a user-marked document including a user-marked response sheet having a response area and at least one image marker, a means for obtaining a digital image of the user-marked response sheet, a computer having programming to perform steps which include identifying three-dimensional position information of the at least one image marker in an obtained digital image, calculating position information of the response area in an obtained digital image using the three-dimensional position information of the at least one image marker, identifying position information of a user created mark within the response area using the calculated position information of the response area, and evaluating whether the position information of the user created mark corresponds with position information of a first predefined mark or a second predefined mark.
