  • Patent number: 9916662
    Abstract: A technique for foreground determination includes analyzing pixels that are deemed to be changing between frames, and applying a filtration technique that is based on fractal methods. Implementations include applying a filter that is designed to eliminate structures of dimensionality less than unity while preserving those of dimensionality unity and greater. The technique may be performed in real-time and makes use of a variable threshold for foreground determination and image segmentation techniques.

  • Publication number: 20170069101
    Abstract: A method and apparatus for unsupervised segmentation of an image is provided. In some exemplary embodiments, the method adjusts a segmentation parameter of a traditional graph-based segmentation algorithm along the image to generate a segmentation map that is perceptually reasonable for a human observer. In some embodiments, the method reduces over-segmentation and under-segmentation of the image.

  • Publication number: 20170046615
    Abstract: Systems and method for object characterization include generating a classifier that defines a decision hyperplane separating a first classification region of a virtual feature space from a second classification region of the virtual feature space. Input information is provided to the classifier, and a number of classifications are received from the classifier. A distribution of the classifications is determined and used to generate a prediction.

  • Publication number: 20160065959
    Abstract: In embodiments, a system for encoding video is configured to receive video data comprising a frame and identify a partitioning option. The system identifies at least one characteristic corresponding to the partitioning option, provides the at least one characteristic, as input, to a classifier, and determines, based on the classifier, whether to partition the frame according to the identified partitioning option.

  • Patent number: 8798966
    Abstract: One embodiment relates to a method of model-based optical metrology. An area of a geometrical structure of dispersive materials on a substrate is illuminated with polarized incident electromagnetic radiation using an illuminator of a scatterometer apparatus. Spectral components of the incident electromagnetic radiation reflected from the area are measured using a detector of the scatterometer apparatus. Using a computer for the scatterometer apparatus, parameter values are determined that minimize an objective function which represents a difference between the measured spectral components and computed spectral components based on a parameterized model of the geometrical structure. Steps for determining the parameter values that minimize the objective function include: computing a solution to state equations driven by a function representing the incident electromagnetic radiation, and computing a solution to an adjoint to the state equations. Other embodiments and features are also disclosed.

  • Publication number: 20120213447
    Abstract: In one embodiment, an image is broken up into multiple regions or segments, where each segment may be of arbitrary shape, and a transform (multi-scale or otherwise) is applied on the set of segments. In another embodiment, pattern adaptive prediction is used when predicting the next finer level of the transform pyramid. The pattern adaptive prediction uses the parent grid to determine what geometry of a filter is to be used when predicting the child grid. At the boundaries of the domain, the pattern adaptive prediction can coupled with the domain adaptive prediction technique.

  • Patent number: 7480047
    Abstract: In an embodiment, a method of time-domain simulation for simulating scattering spectra is described. The method may provide for computing spatial derivatives including computing spectral derivatives in some portion of the domain and finite difference derivatives in some other portion of the domain; forming an equation for non-reflecting boundary conditions; and computing a time-stepping scheme using a high-order unconditionally stable computation method.
