  • Publication number: 20080027171
    Abstract: A polymer includes directly bonded aromatic pendent groups and at least one moiety defined by one of the following formulas >N—N?CR1R2 or —N?N—CR1R2— where R1 and R2 (a) are independently H or a substituted or unsubstituted alkyl, alkenyl, cycloalkyl, cycloalkenyl, aryl, allyl, aralkyl, alkaryl, or alkynyl group, or (b) together form a substituted or unsubstituted alkylene, alkenylene, cycloalkylene, cycloalkenylene, or arylene group. The moiety can be attached to the polymer through one or both of the two open bonds and, where it is attached through only one bond, the other bond attaches to a hydrogen atom, i.e., the moiety is at a terminus of the polymer.

  • Publication number: 20080008249
    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: 7289562
    Abstract: A method for reducing or eliminating coding artifacts in video pictures processed using intra block prediction methods, for example, according to the H.264 standard. The causes of the coding artifacts are identified to be the intra prediction modes with prediction directions that are not in the direction of the raster scan. Filtering the affected blocks with a simple one-dimensional spatial filter will reduce or even eliminate these coding artifacts.

  • Publication number: 20070153897
    Abstract: A fast motion estimation system that determines a reference macroblock or sub-block combination within a reference frame for a current macroblock in a current frame includes a memory, a reference macroblock search circuit, a sub-block combination search circuit, and a comparator circuit. The reference macroblock search circuit determines a motion vector, multiple difference values, and a cost value for each macroblock within the reference frame according to a fast motion estimation search pattern, and stores the motion vector and the difference values in the memory. The sub-block combination search circuit searches the motion vector and the difference values in the memory for determining a corresponding one of multiple lowest cost sub-block combinations for each of multiple sub-block motion modes. The comparator circuit determines a lowest cost macroblock and selects from among the lowest cost macroblock and the lowest cost sub-block combinations to determine the reference macroblock.
