Patent number: 6886912Abstract: This invention relates to a method and apparatus for processing images having color combinations. Such combinations may be embodied in, for example, a black object being printed within a color object or in a black object that includes drops of process color within the object. In these circumstances, undesired image artifacts and halos are eliminated in images that include black portions that are adjacent color portions, and/or improved printed edges are created, by offsetting the corresponding black pixels relative to the color pixels and etching preselected pixels from the image before printing.Type: GrantFiled: January 15, 2003Date of Patent: May 3, 2005Assignee: Xerox CorporationInventor: David A.

Publication number: 20050089059Abstract: A bus communication system capable of determining an order of priorities based on IDs of transmitting nodes is provided. A communication unit writes its own node ID as a transmitting node ID into an arbitration field of a message packet that is to be transmitted from the communication unit to a bus, writes a node ID of a destination node into an auxiliary field defined at a predetermined location in the message packet, and transmits the message packet to the bus. A control unit rewrites the message packet transmitted from the communication unit by replacing the node ID written in the arbitration field with the node ID written in the auxiliary field, and transmits the rewritten message packet to the bus. Another communication unit, or the destination node, receives the message packet existing on the bus based on a match between its own node ID and the node ID indicated in the arbitration field rewritten by the control unit.Type: ApplicationFiled: September 10, 2004Publication date: April 28, 2005Applicant: FUJI XEROX CO., LTD.Inventor: Hiroshi Kurita

Patent number: 6885382Abstract: An image processing device can reproduce the original color of an electronic document on an output device faithfully and can simulate the appearance of color of a recorded product on a display device accurately. Color temperature information of an electronic document is recognized by an electronic document color temperature information recognition unit and delivered to a first color correction conversion unit. The first color correction conversion unit carries out color conversion based on the color temperature information of the electronic document so that a recorded product output from an output device assumes substantially the same color as the electronic document when it is observed under an illumination light source having a color temperature indicated by the color temperature information of the electronic document. An image is formed by the output device based on the color converted image signal to output the recorded product.Type: GrantFiled: August 18, 2000Date of Patent: April 26, 2005Assignee: Fuji Xerox Co., Ltd.Inventors: Tomoyasu Matsuzaki, Hiroaki Ikegami, Hitoshi Ogatsu

Patent number: 6885985Abstract: The invention relates to a method and apparatus for generating translations of natural language terms from a first language to a second language. A plurality of terms are extracted from unaligned comparable corpora of the first and second languages. Comparable corpora are sets of documents in different languages that come from the same domain and have similar genre and content. Unaligned documents are not translations of one another and are not linked in any other way. By accessing monolingual thesauri of the first and second languages, a category is assigned to each extracted term. Then, category-to-category translation probabilities are estimated, and using said category-to-category translation probabilities, term-to-term translation probabilities are estimated. The invention preferably exploits class-based normalization of probability estimates, bi-directionality, and relative frequency normalization.Type: GrantFiled: December 18, 2000Date of Patent: April 26, 2005Assignee: Xerox CorporationInventor: David Hull

Publication number: 20050086224Abstract: A measure of similarity between two documents is computed. In computing the measure of similarity, a first list of rated keywords extracted from the first document and a second list of rated keywords extracted from the second document are received. The first and second lists of keywords are used to determine whether the first document forms part of the second document using a first computed percentage indicating what percentage of keyword ratings in the first list also exist in the second list. A second percentage is computed that indicates what percentage of keyword ratings along with a set of their neighboring keyword ratings in the first list that also exist in the second list when the first percentage indicates that the first document is included in the second document. The first percentage is used to specify the measure of similarity when the second percentage is greater than the first percentage.Type: ApplicationFiled: October 15, 2003Publication date: April 21, 2005Applicant: XEROX CORPORATIONInventors: Alain Franciosa, Christopher Dance
