Patent Images
1. A system for detecting tape on a document, the system comprising:
- a document guide for moving the document in a set path;
an imaging device for capturing images;
a plurality of electromagnetic radiation sources directed toward the document;
a controller communicatively coupled to the plurality of electromagnetic radiation sources and the imagining device; and
wherein the controller includes tape detection application, and wherein the controller running the tape detection application is operable to;
capture a first image of a document, the first image captured while at least a portion of the document is subjected to a first of the plurality of electromagnetic radiation sources,capture a second image of the document, the second image captured while at least a portion of the document is subjected to a second of the plurality of electromagnetic radiation sources, andcomparing the first image to the second image to determine whether tape is adhered to the document.

Abstract
Systems and methods for detecting tape on a document are provided. In one embodiment, a method includes capturing a first image of a document. The first image is captured while at least a portion of the document is subjected to a first electromagnetic radiation. The method includes capturing a second image of the document. The second image is captured while at least a portion of the document is subjected to a second electromagnetic radiation. The method also includes comparing the first image to the second image to determine whether tape is adhered to the document.

9. A method for detecting tape on a document, the method comprising:
-
(a) moving a document along a predetermined path; (b) capturing a first image of the document in response to subjecting at least a portion of the document to a first electromagnetic radiation; (c) capturing a second image of the document in response to subjecting at least a portion of the document to a second electromagnetic radiation; (d) comparing the first image to the second image to form a transformed image, the transformed image associated with a set of intensity values; and (e) determining whether the document includes at least a minimum threshold amount of tape using the intensity values of the transformed image. - View Dependent Claims (10, 11, 12, 13)

14. A method for detecting tape on a document, the method comprising:
-
capturing a first image of a document on a first side, the first image captured while at least a portion of the document is subjected to a first electromagnetic radiation; capturing a second image of the document on the first side, the second image captured while at least a portion of the document is subjected to a second electromagnetic radiation; capturing a third image of a document on a second side, the third image captured while at least a portion of the document is subjected to a third electromagnetic radiation; capturing a fourth image of a document on the second side, the fourth image captured while at least a portion of the document is subjected to a fourth electromagnetic radiation; comparing the first image to the second image to determine whether tape is adhered to the document on the first side; and comparing the third image to the fourth image to determine whether tape is adhered to the document on the second side. - View Dependent Claims (15)
