  • Patent number: 8971738
    Abstract: There is provided a recording medium imaging device capable of properly selecting pixels used for determining the kind of the recording medium from the captured surface image to remove pixels from which the surface property of the recording medium cannot be properly determined because the pixels extremely high in light quantity are affected by some sort of dirt or scratches in determining the kind of a recording medium. This allows the determination of kind of the recording medium based on the normally captured surface image to reduce the decrease in accuracy in determining the kind of the recording medium.

  • Patent number: 8964002
    Abstract: A method for registering a first imaging detector to a surface projects a sequence of k images toward the surface, wherein k?4, wherein each of the k images has a pattern of lines that extend in a direction that is orthogonal to a movement direction. The pattern encodes an ordered sequence of labels, each label having k binary elements, such that, in the movement direction, any portion of the pattern that is k equal increments long encodes one label of the ordered sequence. The method obtains, for at least a first pixel in the first imaging detector, along at least one line that is parallel to the movement direction, a first sequence of k signal values indicative of the k binary elements of a first label from the ordered sequence of labels and correlates the at least the first pixel in the first imaging detector to the surface.

  • Patent number: 8958898
    Abstract: The invention embodies methods and apparatuses to monitor and control the characteristics of a creping process. The method involves measuring optical properties of various points along a creped paper sheet and converting those measurements into characteristic defining data. The invention allows for determining the magnitude and distribution of crepe structures and their frequency and distribution. This allows for the generation of information that is accurate and is much more reliable than the coarse guessing that is currently used in the industry. Feeding this information to papermaking process equipment can result in increases in both quality and efficiency in papermaking.

  • Patent number: 8948462
    Abstract: Technologies are generally described for determining a texture of an object. In some examples, a method for determining a texture of an object includes receiving a two-dimensional image representative of a surface of the object, estimating a three-dimensional (3D) projection of the image, transforming the 3D projection into a frequency domain, projecting the 3D projection in the frequency domain onto a spherical co-ordinate system, and determining the texture of the surface by analyzing spectral signatures extracted from the 3D projection on the spherical co-ordinate system.

  • Patent number: 8937628
    Abstract: A method for determining geometric properties of a target shape such as a shape of a perimeter of a strut shield (36) for use in a gas turbine (10). The method includes obtaining a digital image of at least a portion of a first object including a first feature (164) (106). The image including the first feature (164) is displayed on a display device (108). During a reconstruction process, one or more control points (168A, 168B, 168C, 168D) are associated with feature points (164A, 164B, 164C) along an extent of the displayed first feature (164) (109). Using the associated one or more control points (168A, 168B, 168C and 168D), a data file is created that corresponds to the first feature (164) (114). The data file includes geometric properties of the feature points (164A, 164B, 164C).

  • Patent number: 8896885
    Abstract: A printer with integral scanner for obtaining a digital signature from a sheet of paper or other article as it is printed. The integral scanner has a coherent source which directs a light beam to illuminate the article and a detector arrangement to collect data points from light scattered from many different parts of the article to collect a large number of independent data points, typically 500 or more. The digital signature derived from the data points is stored in a database with an image of what was printed on the article. At a later time, the authenticity of an article purported to be the originally printed article can be verified by scanning the purported genuine article to obtain its digital signature. The database is then searched, to establish whether there is a match. If a match is found, the image stored in the database with the matched digital signature is displayed to the user to allow a further visual check that the article is genuine.
