  • Patent number: 8705857
    Abstract: An image processing system and method corrects the perceptual quality of an image by adjusting the image colors. “Color” in this sense is to be understood as encompassing three-dimensional parameterizations of color, incorporating both intensity and hue. These measurements are made using creative computations developed and adapted from the RETINEX™ theory (Land, 1977), where the RETINEX implementation adjusts any pixel in any direction in color space and further to automatically determine the best direction for it to be adjusted to increase the perceptual visibility of the algorithm with a minimal amount of change to the original image values.

  • Patent number: 8521659
    Abstract: Discovering mixtures of models includes: initiating learning algorithms, determining, data sets including a cluster of points in a first region of a domain and a set of points distributed near a first line extending across the domain; inferencing parameters from the cluster and the set of points; creating a description of the cluster of points in the first region of the domain and computing approximations of a first learned mixture model and a second learned mixture model; determining a first and second probability, generating a confidence rating that each point of the cluster of points in the first region of the domain corresponds to the first learned mixture model and generating a confidence rating that each point of the set of points distributed near the first line correspond to the second learned mixture model, thus causing determinations of behavior of a system described by the learned mixture models.

  • Patent number: 8477147
    Abstract: Methods and systems of representation and manipulation of surfaces with perceptual geometric features, using a computer graphics rendering system, include executing algorithmic instructions to compute a plurality of vertices, edges and surfaces in a mesh for the purpose of defining representations of surfaces on grids. Normals and distances are determined for triangular surfaces to be considered. Additionally, height fields of a function are defined. A set of feature curves and a set of feature points are determined, based on the defined function. Infinitesimal movements along the representations of the surfaces are determined, along with determinations of properties of representations of continuous surfaces. Additional determinations of perceptual geometric features include determinations such as zero crossings, parabolic curves, flecnodes, ruffles, gutterpoints, conical points and biflecnodes in a given mesh.

  • Patent number: 5870136
    Abstract: Methods, systems and computer products are provided for tracking objects within a scene using imperceptible structured light. The imperceptible structured light may be used in environments where humans work and therefore avoids disorienting observers. The structured light patterns are generated dynamically, allowing tracking without physical landmarks. Moreover, the occlusion of the generated landmarks is overcome by determining the position of objects using a determined camera position. The imperceptible structured light may be used in systems without tracking. The tracking may be used without imperceptible structured light.
