  • Publication number: 20200192896
    Abstract: Systems and methods for processing data are disclosed. Methods can include receiving a plurality of data resources from one or more data sources and processing one or more of the plurality of data resources to identify a unique data identifier from one of the plurality of data resources. One or more of the plurality of data resources can be processed to identify one or more data records associated with the unique data identifier. A data sequence can be generated, the data sequence can comprise the unique data identifier and the one or more data records associated with that unique data identifier. A plurality of data sequences can be generated, each of the data sequences can comprise a unique data identifier and the one or more data records associated with that unique data identifier.

  • Patent number: 9928187
    Abstract: What is disclosed is a system and method for increasing throughput in the image processing path of a digital document reproduction device. A digital image to be processed is received. Memory is allocated into two buffers, B[0] and B[1]. Each buffer has size S B ? M 2 , where M is a size of the allocation. The digital image is divided into N number of tiles. Then, for tiles Ti, where i=1 to N: (A) the image data of tile Ti is decompressed into buffer B[((i% 2)=0], and (B) the image data of buffer B[(i% 2)?0] is decompressed into the image path pipeline. Send a signal indicating that processing of the digital image has completed.

  • Publication number: 20160203392
    Abstract: Techniques related to hybrid draft mode printing are discussed. Such techniques may include rendering sections of a print job document for printing based on different render settings to provide a print ready document having low print quality areas and high print quality areas. Printing such documents for review, for example, may provide consumables savings, review improvement, and review cycle time reduction.

  • Patent number: 9357101
    Abstract: An image processor determines the number of pixels to be added/removed within each row/column of pixels of an image to accomplish a given image enlargement/reduction. The image processor evenly distributes pixels that are to be added/removed along the full length of each of the rows or columns of pixels, and adds/removes pixels in a process that identifies a set of original pixels that are immediately adjacent to the pixel to be added/removed. The image processor then replaces each of the sets of the original pixels with a replacement set (that has one more/less pixel relative to the set of original pixels). Also, for each pixel that will be added/removed, the image processor determines data values for replacement pixels in each of the replacement sets by weighting data values from original pixels in the sets of original pixels. The image processor outputs an enlarged/reduced size version of the input image.

  • Patent number: 9262704
    Abstract: Methods and systems render higher bit per pixel contone images to lower bit formats using multiple registers of a SIMD processor. The rendering process uses a first register to maintain contone image values of all the pixels being simultaneously processed. A second register maintains a threshold value used during the conversion process. A third register maintains one value for the print ready format pixels (e.g., those having less bits per pixel), and a fourth register maintains the other value (e.g., 0) for the print ready format pixels. Also, a fifth register maintains the conversion error amount for all the pixels being simultaneously processed. Sixth through ninth registers maintain distributed conversion error amounts produced by the diffusing process (for different pixels being simultaneously processed); and a tenth register maintains the pixels in the print-ready format produced by the conversion for all the pixels being simultaneously processed.

  • Publication number: 20140317998
    Abstract: Methods and systems for processing crude oil may include adding water to crude oil, for example, in a desalter, to produce hydrocarbon and brine and a rag layer emulsion, which may include hydrocarbon and brine and solids. The emulsion may be modified, including adding one or more of additional hydrocarbon and, a demulsifier, a reverse demulsifier, a coagulant, and a flocculant, for example, in a mixer. The modified emulsion may be directed through a dead-end filter assembly to remove solids.

  • Patent number: 8842938
    Abstract: Methods and systems for performing resolution expansion with high quality edge enhancement capability utilizing an edge detector and a color estimator. An edge tag with respect to an input image can be detected via an edge detector and an edge detection approach. A resolution expansion can be separately applied to the edge tag and a binary output generated by other processing functions. Multiple output lines corresponding to the input image from the color estimator with different threshold array values for an edge pixel can be generated by a halftoning module. A binary domain resolution expansion can be applied for a non-edge pixel. A final output for each pixel can be selected from a resolution expanded result and/or from the result of the halftoning for the edge based on the edge tag with respect to that pixel.

  • Patent number: 8482801
    Abstract: A method and system for processing image data in an image processing device for a plurality of pixel positions within a plurality of scanlines. The method and system includes storing a starting stamp value and a plurality of delta stamp values for the scanline. The stored values being used to generate a pixel stamp value for an input pixel in the scanline, by adding a starting value or previous pixel stamp value and the stored delta stamp value for the input pixel. Further includes receiving an input pixel intensity value for the input pixel and determining an output pixel intensity value. Subsequently, if the output pixel intensity value for the input pixel is equal to a value for a dot or hole the delta stamp values for at least one pixel having a location previous or subsequent to the input pixel can be updated.
