  • SYSTEMS AND METHODS FOR DETECTING TAPE ON A DOCUMENT
    Publication number: 20150310689
    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.

  • Systems and methods for detecting an optically variable material
    Patent number: 8433124
    Abstract: Systems and methods for detecting an optically variable material are provided. According to an illustrative embodiment, a method for detecting an optically variable material includes capturing a first image of at least a portion of a document while the at least a portion of the document is subjected to a first electromagnetic radiation from a first angle of incidence, and capturing a second image of at least a portion of the document while the at least a portion of the document is subjected to a second electromagnetic radiation from a second angle of incidence. The first angle of incidence is different from the second angle of incidence. The first and second images are captured by an imaging device that has substantially fixed position. The method also includes comparing the first image to the second image to determine whether an optically variable material is present on the document.
