  • Patent number: 8180962
    Abstract: Since the threshold excess is judged by a value of high-workload IO of backup that is designed on the assumption that the workload of storage is high, whether the performance limit has been reached remains uncertain. Furthermore, although an optimistic prediction trend with low workload trend and a pessimistic prediction trend with high pessimistic workload trend are presented, LUs that require improvement remain uncertain. Moreover, the time to improve the configuration and the effect of the improvement remain uncertain. To improve the configuration, configuration information, performance information, and operation information are acquired from storage, a performance limit excess time is predicted based on the performance information excluding LUs exceeding the performance trend, and an optimal improved configuration is determined from the performance limit after improvement and the time required for the improvement.

  • Patent number: 8165403
    Abstract: A pose of an object is determine by acquiring sets of images of the object by a camera, wherein the object has a thread arranged on a surface such that a local region of the object appears substantially spherical, wherein the camera is at a different point of view for each set, and wherein each image in each set is acquired while the scene is illuminated from a different direction. A set of features is extracted from each image, wherein the features correspond to points on the surface having normals towards the camera. A parametric line is fitted to the points for each image, wherein the line lies on a plane joining a center of the camera and an axis of the object. Then, geometric constraints are applied to lines to determine the pose of the object.

  • Publication number: 20110316968
    Abstract: A single camera acquires an input image of a scene as observed in an array of spheres, wherein pixels in the input image corresponding to each sphere form a sphere image. A set of virtual cameras are defined for each sphere on a line joining a center of the sphere and a center of projection of the camera, wherein each virtual camera has a different virtual viewpoint and an associated cone of rays, appearing as a circle of pixels on its virtual image plane. A projective texture mapping of each sphere image is applied to all of the virtual cameras on the virtual image plane to produce a virtual camera image comprising circle of pixels. Each virtual camera image for each sphere is then projected to a refocusing geometry using a refocus viewpoint to produce a wide-angle lightfield view, which are averaged to produce a refocused wide-angle image.
