  • Patent number: 7822292
    Abstract: Systems, methods, and apparatus, including computer program products, are provided for forming composite images. In some implementations, a method is provided. The method includes receiving a set of component images for forming a composite image, defining a projection for the set of images transforming each component image into a projected component image, and rendering the projected component images to form the composite image. The rendering of each component image includes decomposing a rotation of the projection into separate rotations for each axis, rotating the component image along a first axis, separately identifying pixel values for each row and each column of the projected component image, and rotating the image along a third axis to form a rendered component image.

  • Patent number: 7813594
    Abstract: A system and method for managing the archival and retention of data in a multiple-node PACS network. Data is distributed among network nodes such that a secondary node will not delete a received image study it has received from a primary node if the primary node is an originating source. Instead, the secondary node will execute data retention. Data retention is achieved by including a delete retention attribute within the metadata associated with the received image data on the secondary node and requiring that the secondary node enforce data retention if a data retention attribute is identified within the metadata stored on the secondary node.

  • Patent number: 7813596
    Abstract: A system and method synthesizing images of a locale to generate a composite image that provide a panoramic view of the locale. A video camera moves along a street recording images of objects along the street. A GPS receiver and inertial navigation system provide the position of the camera as the images are being recorded. The images are indexed with the position data provided by the GPS receiver and inertial navigation system. The composite image is created on a column-by-column basis by determining which of the acquired images contains the desired pixel column, extracting the pixels associated with the column, and stacking the columns side by side. The composite images are stored in an image database and associated with a street name and number range of the street being depicted in the image. The image database covers a substantial amount of a geographic area allowing a user to visually navigate the area from a user terminal.

  • Patent number: 7809207
    Abstract: Methods for pre-processing video sequences prior to compression to provide data reduction of the video sequence. Also, after compression of the pre-processed video sequence, the bit rate of the pre-processed and compressed video sequence will be lower than the bit rate of the video sequence after compression but without pre-processing. Pre-processing may include spatial anisotropic diffusion filtering such as Perona-Malik filtering, Fallah-Ford filtering, or omni-directional filtering that extends Perona-Malik filtering to perform filtering in at least one diagonal direction. Pre-processing may also include performing filtering differently on a foreground region than on a background region of a video frame. This method includes identifying pixel locations having pixel values matching characteristics of human skin and determining a bounding shape for each contiguous grouping of matching pixel locations.

  • Patent number: 7809210
    Abstract: Systems and methods are provided that facilitate grey level magnification to improve details and contrast for a dark scene of video on a digital display system. Preferably implemented over a limited pixel level range, the video enhancement process counts the number of pixels corresponding to each level within the range in a frame and then, based on the percent level distribution of the pixels, calculates the stack of percentage distribution. From the stack of percentage distribution, a transformation process is performed to reassign the pixel values over a dark level range and to expand the distribution of the pixels. The result of transformation enhances the details and contrast of the dark area significantly without affecting the bright scene. By only applying the algorithm to dark scenes, computation loads are reduced compared with some of the full picture processing methods. Lower computational loads are important to reduce motion artifacts in high speed video applications.

  • Patent number: 7792338
    Abstract: A method and apparatus for creating a magnified composite image of a microscope specimen comprises making error corrections for imprecise movements of the specimen relative to an objective lens when capturing data for first and second images. A correction offset is computed based on a comparison of data for overlapped portions of the first and second images and then the specimen is moved through a distance modified by the correction offset for capture of a subsequent tiled image. Image center portions are retained as the data structure tile. The area about the center portion is used to align images and to compensate for stage inaccuracies and to provide a feedback signal for a drive system. Differences in X, Y coordinates for macro and micro view images may be used as navigation offsets to view a selected point for the micro image marked on the macro image.
