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;
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,comparing the first image to the second image to determine whether tape is adhered to the document; and
wherein controller is configured to capture the first image of the document with a first plurality of line images that form the first image, wherein controller is configured to capture the second image of the document with a second plurality of line images that form the second image, and wherein each line image is an image of a vertically spread line of sight of a segment of the document that is less than a whole of 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.

8. 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, wherein the first image of the document is captured with a first plurality of line images that form the first image; (c) capturing a second image of the document in response to subjecting at least a portion of the document to a second electromagnetic radiation, wherein the second image of the document is captured with a second plurality of line images that form the second image, and wherein each line image in (b) and (c) is an image of a vertically spread line of sight of a segment of the document that is less than a whole of the document; (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 (9, 10, 11, 12)

13. 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; wherein the steps of capturing a first image, capturing a second image, capturing a third image, and capturing a fourth image of the document comprises in each instance capturing a respective image using a plurality of line images, and wherein each line image is an image of a vertically spread line of sight of a segment of the document that is less than a whole of the document; 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 (14)
