Patent number: 6626512Abstract: A method of printing a subject on a medium by use of a printing device including a printhead assembly, wherein the printhead assembly has at least one printhead having an array of marking elements, is accomplished by scanning the printhead assembly along a medium by a succession of passes, the passes being offset from each other in a direction transverse to a scanning movement of the printhead assembly relative to the medium. The subject consists of textual and non-textual material, and pixels of the subject are loaded into the printing device. The method provides for separating pixels of the textual material from pixels of the non-textual material, and printing pixels of at least a portion of the subject by passing the printhead along the medium in a plurality of the passes. In an offsetting of successive ones of the passes, a translation of the printhead in the transverse direction accumulated over the succession of the plurality of passes does not exceed a transverse dimension of the printhead.Type: GrantFiled: March 19, 2002Date of Patent: September 30, 2003Assignee: Xerox CorporationInventor: Steven Jay Bloomberg

Patent number: 6628843Abstract: A method and apparatus are provided for enhancing JPEG compressed digital image data wherein only the DC components of the compressed image data are required to obtain a statistical subsampling of the corresponding uncompressed image data. JPEG compressed image data are received that represent an input digital image, and the JPEG compressed image data include a plurality of DC components. DC components are extracted from the JPEG compressed image data, and the extracted plurality of said DC components represent a subsampling of the input digital image. At least some of the plurality of extracted DC components are input to an automated image enhancement system.

Publication number: 20030182631Abstract: Systems and methods for determining the topic structure of a document including text utilize a Probabilistic Latent Semantic Analysis (PLSA) model and select segmentation points based on similarity values between pairs of adjacent text blocks. PLSA forms a framework for both text segmentation and topic identification. The use of PLSA provides an improved representation for the sparse information in a text block, such as a sentence or a sequence of sentences. Topic characterization of each text segment is derived from PLSA parameters that relate words to “topics”, latent variables in the PLSA model, and “topics” to text segments. A system executing the method exhibits significant performance improvement. Once determined, the topic structure of a document may be employed for document retrieval and/or document summarization.Type: ApplicationFiled: March 22, 2002Publication date: September 25, 2003Applicant: XEROX CORPORATIONInventors: Ioannis Tsochantaridis, Thorsten H.

Automatic restacking tray side guide repositioning system providing sheet stacking scatter reduction
Publication number: 20030180078Abstract: In a document feeder with a superposed sheet input tray and sheet output stacking tray for feeding and then restacking print media paper sheets of variable dimensions, the lateral setting (repositioning) of the at least one variable position side guide of the input tray to the sides of the input sheets automatically correspondingly resets the corresponding side guide of the underlying output stacking tray, to reduce sheet scattering in the sheet stacking, especially skewed sheets. This may be accomplished by a simple direct mechanical integration of these respective side guides into a single repositionable component with upper and lower extending sheet edge guide portions.Type: ApplicationFiled: March 20, 2002Publication date: September 25, 2003Applicant: Xerox CorporationInventors: Donald J.
