摘要： A three or more dimensional (3+D) graphical user interface (GUI) uses detected three dimensional (3D) hand movements or other input devices to navigate a displayed two dimensional (2D), three dimensional, or 3+D representation of a corresponding menu, document, or data set. Specific hand motions may be used that correspond to navigational commands, including, but not limited to: up, down, left, right, select, exit, back, new search, start, close, and deselect. The GUI displays two initially perpendicular axes, with additional axes sufficiently off angle that their navigation is apparent, rather than hidden. The 3+D GUI may be used for navigating large complex data sets, such as search results, document library storage, or simpler data sets, such as TV menus, music selection, photographs, videos, etc.

摘要： A method of evaluating halo artifacts is described herein. The method utilizes a pattern of color patches, a color space and color difference metrics to analyze color changes which correlate to the amount of halo. The pattern of color patches is utilized in the CIE L*a*b* color space to determine an area of patch unaffected by halo of the pattern of color patches. After the area of patch unaffected by halo is determined, a Reference Value is computed by averaging the CIE L*a*b* color for the area of patch unaffected by halo. Then an Artifact Value is calculated either by averaging the CIE L*a*b* color for the area outside the area of patch unaffected by halo but before the margin or by averaging the CIE L*a*b* color on the edge of the patch. Once these values are determined, the halo quantity is calculated.

摘要： A noise prediction scheme provides a method of predicting an output noise variance resulting from a spatial filtering transformation. For a given input image signal with a known input noise variance, a periodic model is developed. The periodic model defines periodic boundary conditions for the input image signal based on the principal that the input image signal is repeated in each direction. In this manner, pixel values are defined about either side of the input image signal boundaries in either one, two, or three dimensions. A spatial filtering transformation includes convoluting the input image signal with an impulse response of a filter. Autocavariances at different points in time or lags of the input image signal are also determined. The number of autocovariances is determined by the nature of the spatial filtering transformation. The noise prediction scheme predicts an output noise variance resulting from the spatial filtering transformation based on the input noise variance, the autocovariances, and the periodic boundary conditions of the input image signal.

摘要： Pairs of stereo Xray radiographs are obtained from an X-ray imaging system and are digitized to form corresponding pairs of stereo images (602, 604). The pairs of stereo images (602, 604) are adjusted (410) to compensate for gray-scale illumination differences by grouping and processing pixel groups in each pair of images. Distortion in the nature of depth plane curvature and Keystone distortion due to the toed-in configuration of the X-ray imaging system are eliminated (412). A screen parallax for the pair of stereo images is adjusted (414) to minimize depth range so as to enable a maximum number of users to view the stereoscopic image, and particular features of interest.

摘要： A stereo radiograph is produced in a radiography system including an anti-scatter grid (105) and sensor material (107). At least one x-ray beam (102) is emitted towards a body to be radiographed (103). The anti-scatter grid (105) is focused so as to transmit two distinct x-ray beams (106) to the sensor material (107). The transmitted beams (106) create two alternating images on the sensor material (107). A stereo radiograph is created from the two alternating images. System geometry of the radiography system is used to determine location of an object (606) within a radiographed body (103), and to determine distance (613) between a chosen point and an object (606) within a radiographed body (103).
