  • Publication number: 20130094780
    Abstract: Disclosed herein are a system and a method that use a background model to determine and to segment target content from an image and replace them with different content to provide a composite image. The background model can be generated based on image data representing images of a predetermined area that does not include traversing content. The background model is compared to image data representing a set of captured images of the predetermined area. Based on the comparison, portions of an image that differs from the background model are determined as the traversing content. A target content model is used to determine the target content in the traversing content. The target content determined in the images is replaced with different content to provide a composite image.

  • Publication number: 20120110541
    Abstract: Functionality can be implemented for optimizing connection constraints in an integrated circuit design. A target timing path associated with a first of a plurality of sub-connections of the integrated circuit is determined. A timing probability value and a route probability value associated with the first of the plurality of sub-connections is determined based, at least in part, on the target timing path associated with the first of the plurality of sub-connections. The timing probability value indicates a probability that timing closure is satisfied on the target timing path. The route probability value indicates a probability that a physical routing track on the target timing path associated with the first of the plurality of sub-connections resolves congestion. A current connection constraint associated with the first of the plurality of sub-connections is modified in accordance with a connection constraint model to which the first of the plurality of sub-connections corresponds.

  • Publication number: 20120093408
    Abstract: A local image patch identified in an image is divided into respective sub-patches of respective image forming elements. For each of the respective image forming elements in the local image patch, a respective ordinal rank of the image forming element is determined, and respective contributions of the image forming element to a particular one of the respective sub-patches containing the image forming element and to one or more other ones of the respective sub-patches neighboring the particular sub-patch are ascertained. Each ordinal rank corresponds to a respective dimension of an ordinal rank feature space. For each of the respective sub-patches of the local image patch, a respective histogram of ascertained contributions of the image forming elements in the ordinal rank feature space is built. A respective feature vector representing the local image patch is generated from the respective histograms built for the sub-patches of the local image.
