Publication number: 20070104390Abstract: Algorithms to show multiple images at the maximum possible resolution are proposed. Rather than reducing the resolution of each image, the portion of each image that is actually shown is reduced. The algorithms select which part of each image is to be shown. In one embodiment of the invention, changing the parameters over time further increases the information displayed.Type: ApplicationFiled: April 17, 2006Publication date: May 10, 2007Applicant: Fuji Xerox Co., Ltd.Inventor: Jonathan Foote

Publication number: 20070103731Abstract: A method and system to convert an image described in a page description language to a contone image. The contone image is halftoned and encoded to generate image data including edge tag data and image data. A tagged state value of each pixel of image data within a predefined neighborhood of pixels is determined. The image data is filtered using a predetermined set of filter weighting values wherein each pixel of image data within the predefined neighborhood of pixels has an associated filter weighting value. A predetermined filtered image value is assigned to each pixel having a tagged state indicating an edge pixel. A summation of all filtered image values for the predefined neighborhood of pixels is assigned when the tagged state of the pixel is a non-edge pixel.Type: ApplicationFiled: November 7, 2005Publication date: May 10, 2007Applicant: Xerox CorporationInventors: Francis Tse, Ramesh Nagarajan

Publication number: 20070106819Abstract: A client-side handheld device requests a server to convert server-side documents into a compression format prior to transmission of said documents to the client. The server retrieves and converts the requested documents to a raster image that is then compressed according to attributes based on information received from the client device in the initial document request. Instead of having to manipulate multiple formats which the original documents are in and supported by the server, the client-side device is preferably optimized in hardware and/or software to support and otherwise take advantage of the requested compression format. The compressed document is then delivered to the client device, in whole or in part, selectively or progressively over time per individual requests prior to displaying the received data to the end-user. Depending on the requested delivery mode, server-side documents are preferably compressed using wavelet compression methods, such as the JPEG 2000 standard, known in the arts.Type: ApplicationFiled: December 22, 2006Publication date: May 10, 2007Applicant: Xerox CorporationInventors: Robert Buckley, Emil Rainero, James Reid, Pamela Spiteri

Patent number: 7215817Abstract: What is disclosed is a decoding method for retrieving information bits encoded in a printed image comprising the steps of first receiving an input electronic image as a scanned version of the printed image. A region of interest in the image is then extracted and, for that region, an amount of K colorant present, denoted KH; is obtained. Further, a color value is generated therefrom and the GCR used for encoding that region is determined using KH and the obtained color value. Encoded information bits are retrieved therefrom based on the determined GCR. The estimated KH is preferably evaluated conditional to a capacity signal KL and a luminance signal L. From the obtained data, values of KH, KL, and L, are derived wherein KH is estimated from a high resolution scan, and KL and L are estimated from a down-scaled image, respectively. The capacity signal KL and the luminance signal L are derived from the obtained color value.Type: GrantFiled: August 20, 2003Date of Patent: May 8, 2007Assignee: Xerox CorporationInventors: Ricardo L. de Queiroz, Robert P.

Patent number: 7215444Abstract: Conventional design tools were not developed for designing square zero-shift supercells. Conventionally, solutions that enable square zero-shift supercells were found by trial and error or by exhaustive analysis. According to a first design criterion of this invention, a non-square supercell in a first frame of reference has a diagonal that is equal in length to the diagonal of a square supercell in a second frame of reference rotated at a desired screen angle to the first frame of reference. The screen angle is a function of the lengths of the sides of the non-square supercell in the first frame of reference. According to a second design criterion, if the area of the corresponding square supercell in the second frame of reference is an integer, a square zero-shift supercell can be designed based on the lengths of the sides of the non-square supercell in the first frame of reference.Type: GrantFiled: July 16, 2002Date of Patent: May 8, 2007Assignee: Xerox CorporationInventor: Charles M.
