    摘要: A method and system for efficient scaling in the transform domain, wherein transform coefficient data is provided as an input to a data processing system and scaled in the transform domain by application of a combined matrix. Some embodiments utilize discrete cosine transform data. One embodiment of the invention generates a combined matrix for one-dimensional scaling by selecting a rational scaling factor and matrix dimension value, generating a matrix with some zero values, applying a one-dimensional inverse transform, regrouping, and applying a one-dimensional forward transform. One application of the invention performs up-scaling operations, and another performs down-scaling operations. The invention also provides for two-dimensional scaling by selecting horizontal and vertical scaling parameters and generating first and second combined matrices responsive to the parameters and combining them into a single combined matrix. The invention may also incorporate a predetermined cost function.

    摘要: A method and system for a printing device is disclosed. The method and system comprise printing a test pattern on a print medium and generating a digital image of the printed test pattern by an imaging device. The method and system include analyzing an interference pattern to measure for distortion of the print medium and calibrating the printing device based upon the measured distortion. In a preferred embodiment, the present invention utilizes the reticle patterns, which are printed in the margins of the paper, which are measured real-time during printing. The interference or Moiré patterns created by superimposed reticles may be used to measure image distortion, process direction misalignment, and misregistration caused by web distortion. The advantage of this invention is that image distortion compensation, RIP (Raster Image Processor) parameters, timing, or other printer characteristics may be adjusted on-the-fly in a closed feedback system, for high-speed textile or paper color printing, utilizing on-the-fly distortion or stretch measurement for accurate color and/or duplex images registration. In a duplex printer, automatic images alignment front-to-back is obtained by combining optically or logically the two images for the evaluation of interference patterns and amount of distortion in the process and scan direction.

    摘要: A soft-decision modulation system (10) has a transmitter (11) and a receiver (21). The transmitter encodes (68), modulates (72) and transmits (74-78) a data stream. The receiver receives the modulated data stream and recovers symbols (86) representing the transmitted data stream. Data decoding (92) is performed with a trellis decoder with a soft-decision metric using a selected set of coefficients (90). The performance of the decoding step is evaluated (104). The coefficients are adjusted (108) until performance is acceptable. When performance is satisfactory the coefficients are installed (112) in the modulation system.

    摘要: A method and system for analyzing impact of change in an organizational entity. A graph H includes nets, nodes of the nets, edges connecting the nodes, and edge weights for the edges. The edge weights denote changes in some nodes resulting from changes in other nodes. For a given set Z of nodes A and for each node B characterized by a set S of at least one path of edges connecting nodes of H from node A to node B for each node A of Z, a measure M(Z,B) of a change in node B resulting from a change in each node A of Z is determined. M(Z,B) is a function of the edge weights in each path of S. Each node B of H is displayed via a graphical representation G(B) assigned to each node B. G(B) is a function of M(Z,B).

    摘要: System and method for rasterizing and encoding multi-region data. In one aspect, a rasterizer derives descriptive information from print data stream (PDS) data, where the descriptive information includes a designation of at least one region of text data in the PDS data, and bitmap data depicting the region of text data. The bitmap data is provided to an encoder without including the bitmap data in a rasterized page bitmap of the PDS data, and the bitmap data is encoded into compressed data using the encoder and a compression format suitable for text data. In another aspect, regions of data are compressed using descriptive information provided from a rasterizer to an encoder via an application program interface
