  • Patent number: 8155189
    Abstract: A method of making a coding mode decision for a current macroblock of a current video frame including determining an INTERSAD value, selecting at least one video characteristic associated with the current video frame, comparing the INTERSAD value with a corresponding range of each selected video characteristic, selecting interframe coding if the INTERSAD value is within the corresponding range of each selected video characteristic, performing intraframe prediction to provide an intraframe prediction macroblock and determining an INTRASAD value if the INTERSAD value is an outlier of any selected video characteristic, selecting intraframe coding if the INTERSAD value is greater than the INTRASAD value and otherwise selecting interframe coding. The video characteristics may be based on any combination of an average of interframe differential sums, a sum of absolute differences between each pixel value of the current macroblock and a mean pixel value of the current macroblock, and a quantization parameter.

  • Patent number: 8120660
    Abstract: Forming image information of image units (e.g. pixels) of a higher resolution by convoluting information of image units of a lower resolution with coefficients of a multiphase filter. The information of one set of higher resolution image units is formed by convoluting in a first direction the information of the lower resolution image units with a first set of four coefficients. The information of a second set of higher resolution image units is form by convoluting in the first direction the information of the lower resolution image units with a second set of four coefficients. Convolution may also be performed in a second direction with a set of four coefficients. In one example, the image information formed includes intensity information for each image unit.

  • Patent number: 8114921
    Abstract: A macromolecule includes a polymer directly tethered or bonded to a polyatomic functionality. The polyatomic functionality can be located at a terminus of the polymer and can be generated concurrent with or soon after formation of the polymer. The macro-molecule can be prepared from a functionalized polymer by hydrolyzing and condensing (e.g., by a sol-gel process) functionalities in which one or more alkoxy groups are bound to a silica atom in the presence of an excess of a compound that includes a Si, Ti, Zr, Sn, Al, or Fe atom. Such macromolecules can be used in the manufacture of vulcanizates and tire components, either alone or blended with other polymers and/or other particulate fillers.
