  • Patent number: 8131096
    Abstract: Coding quantized transform coefficients as occur in image compression combines a position identifying method to identify the relative position of clusters of consecutive non-zero-valued coefficients, an amplitude event identifying method to identify amplitude events in the clusters of non-zero-valued coefficients, and a coding method to code the position events, amplitude events, and signs of the amplitudes in the clusters. The method is particularly applicable to a series of quantized transform coefficients where clusters are likely-to-occur.

  • Patent number: 8103111
    Abstract: In a method of coding light ray information including information about a position on a predetermined surface and information about an incident angle to the surface when a ray of light from a subject enters the surface, the light ray information is divided into two or more processing unit blocks. In a first coding process, coding are executed for each of the two or more processing unit blocks, and first block unit information composing first image information about the subject is obtained. In a second coding process, coding are executed for each of the two or more processing unit block, and second block unit information composing second image information different types from the first image information is obtained.

  • Patent number: 8103057
    Abstract: A system for capturing images of a target area on which information is recorded includes a boom assembly adapted to extend outwardly from a generally vertical surface. At least one digital camera is mounted on the boom assembly at a location spaced from the surface. The at least one digital camera is oriented so that the field of view thereof encompasses a target area on the surface. A controller is in communication with the at least one digital camera. The controller conditions the at least one digital camera to acquire an image of the target area. The image acquired by the at least one digital camera is conveyed to the controller and is processed to determine if an obstacle blocking the target area is in the captured image. If so, the captured image is not further processed and additional images are acquired until an image of the target area is captured without the obstacle therein.

  • Patent number: 8086071
    Abstract: Disclosed are a system and method for identifying objects in an image dataset that occlude other objects and for transforming the image dataset to reveal the occluded objects. In some cases, occluding objects are identified by processing the image dataset to determine the relative positions of visual objects. Occluded objects are then revealed by removing the occluding objects from the image dataset or by otherwise de-emphasizing the occluding objects so that the occluded objects are seen behind it. A visual object may be removed simply because it occludes another object, because of privacy concerns, or because it is transient. When an object is removed or de-emphasized, the objects that were behind it may need to be “cleaned up” so that they show up well. To do this, information from multiple images can be processed using interpolation techniques. The image dataset can be further transformed by adding objects to the images.

  • Patent number: 8055102
    Abstract: A vector interpolator optimizes the conversion of an interlaced signal to a non-interlaced signal. The vector interpolator improves the visual clarity of slanted features in a displayed image by adjusting the luminance value of each pixel such that the appearance of “steps” or “jaggies” in the features is reduced. For each pixel, the vector interpolator determines a similarity measure for the pixels within a predetermined area around the pixel. From the similarity measure, an angle for interpolation is selected. The luminance value is then interpolated along the selected vector corresponding to the angle and applied to the pixel. One or more ambiguity measures such as a local edge count ambiguity measure may also be computed to indicate the reliability of the computed luminance value.

  • Patent number: 6031940
    Abstract: A video data encoding system and method represents video frame image by an initial array of data. The image data array is processed by a wavelet transform function to produce an array of transform coefficients, sometimes called a processed image data array. The processed image data array is divided into subarrays and each subarray is encoded by generating a plurality of encoded representations of the subarray, and then selecting and outputting the smallest of the encoded subarray representations. The plurality of encoded representations are generated by encoding the subarray using a predefined coding technique; generating a differential array that is equal to the difference, on a coefficient by coefficient basis, between the subarray of transform coefficients and the corresponding subarray from a prior video frame; and encoding the differential array. Each encoded subarray is preceded by a flag to indicate if the encoded data represents the subarray or the differential array.
