  • Publication number: 20120189193
    Abstract: The invention relates to computer vision, in particular detection and classification of objects captured in a video stream of images. The invention provides a memory efficient method of storing images that have been pre-processed for use in object detection. The method is based on using histograms of orientation. The invention also includes methods for training and using weak classifiers that use this pre-processing of images. A first weak classifier uses the total count of two orientation values in a histogram as an index to a two dimensional confidence table to determine a confidence value. The second weak classifier projects one or more total counts of orientation values in a histogram into a scalar value that is then used in a one dimensional confidence map to determine a confidence value. Aspects of the invention include methods, computer systems and software.

  • Patent number: 7958001
    Abstract: Stored in a computer are scores related to answers given by human representatives of organizational units in response to defined questions. For the organizational units, total scores and weighted total scores are calculated. The weighted total scores are calculated by adding up weighted maximum scores assigned to the questions, the weighted maximum scores depending on the respective organizational unit and the respective question. Competence levels of the organizational units are calculated by scaling the total scores of the respective organizational unit to a scale of competence reaching from zero to a maximum competence. The maximum competence corresponds to the weighted total score calculated for the respective organizational unit. The computer generates a graphical representation of the competence levels for multiple organizational units of a particular organization.

  • Patent number: 7876448
    Abstract: To measure a sum of electrical currents in different conductors, light is led in an optical sensing fiber around all the conductors. The sensing fiber can be wound around the conductors in a single loop or in several individual loops. Interspersed polarization maintaining fibers and retarders can be used to transfer the light between individual loops for preventing undesired signals from stray magnetic fields. The method has high accuracy is particularly suited for measuring large currents that sum up to zero.
