Patent number: 8117134Abstract: A system calculates appropriate billing within an imaging pipeline. An input component receives an image that is described as a plurality of pixels. A PDL component receives the image and determines a location, a color and a designation for each of the one or more pixels. A marking engine modifies the one or more pixels based at least in part on the location and the color provided by the PDL component and places each of the one or more pixels as a monochrome or a composite pixel on a substrate. An analysis component counts the number of monochrome and composite pixels placed on the substrate by the marking engine, the number of composite pixels that include a designation are counted as monochrome. A billing component calculates the cost for placing each of the monochrome and the composite pixels counted by the analysis component.Type: GrantFiled: October 16, 2008Date of Patent: February 14, 2012Assignee: Xerox CorporationInventors: James B.

Patent number: 8023150Abstract: A method and system reconstructs a contone image from a binary image by first tagging pixels to identify one of a multiplicity of image content types. The tag information and the pattern of bits surrounding the pixel to be converted to a contone value are used to reconstruct a contone image from a binary image. The pattern of bits in the neighborhood is used to generate a unique identifier. The unique identifier is used as the address for a lookup table with the contone value to be used wherein each lookup table corresponds to an image context type.Type: GrantFiled: March 8, 2010Date of Patent: September 20, 2011Assignee: Xerox CorporationInventors: Ramesh Nagarajan, Francis Kapo Tse, Chia-Hao Lee, John Christopher Cassidy, John W.

Publication number: 20110026814Abstract: A method and system for processing image data provides associated background metadata in a searchable format and reduces file size. MRC techniques are used to process input image data. It is known that the image data may be segmented to generate a background layer representing background attributes of the input image data. A background color value of the background layer is detected, and background metadata representing the color value is generated. The background metadata is associated with the image data (e.g., as a separate file, in the image header, etc.), thereby making the background metadata searchable and reducing the file size of the image data to be stored.Type: ApplicationFiled: July 29, 2009Publication date: February 3, 2011Applicant: XEROX CORPORATIONInventors: Robert Eero NUUJA, Francis Kapo Tse, Amal Z.

Publication number: 20110007334Abstract: What is disclosed is a novel system and method for text vectorization for bitmap images with reduced artificial discontinuities. Dominant points are identified in a bitmap character image. An initial curve is fitted to edge points of the character image in a vicinity of a selected dominant point. A set of boundary parameters in a vicinity of the selected dominant point are estimated based upon the initial curve. The selected dominant point is then classified as one of a sharp dominant point and a smooth dominant point based upon the boundary parameters or alternatively upon predefined classifications produced by an optical character recognition process. Curves are fitted between the selected dominant point and adjacent dominant points. The fitted curves maintain the estimated boundary parameters in the vicinity of smooth dominant points. A vectorized representation of the text character image based upon the fitted curves is produced as output.Type: ApplicationFiled: July 7, 2009Publication date: January 13, 2011Applicant: Xerox CorporationInventors: Zhigang Fan, Francis Kapo Tse, Bingfeng Zhou, Yadong Mu, He Tao
