Patent number: 8092963Abstract: The present disclosure provides processes for producing images of excellent color fidelity when incorporating a magenta toner with a lower colorant loading in addition to a first magenta toner. In embodiments, the magenta pigmented particles may be magenta emulsion aggregation toners. In accordance with the present disclosure, a pair of magenta toners are matched in color, wherein the color of a first magenta toner printed at a predetermined halftone area coverage on a substrate substantially matches the color of the solid (100%) printed patch of the second magenta toner, which is lighter than the first magenta toner, thus avoiding a visible hue shift on the print that would otherwise be objectionable.Type: GrantFiled: January 19, 2010Date of Patent: January 10, 2012Assignee: Xerox CorporationInventors: Daryl W.

Patent number: 8094973Abstract: A method, computer readable medium, and computing device for resizing images. A digital image arranged in a rectangular array of pixels is received for resizing in either a horizontal direction or a vertical direction. An energy value is computed for each of the pixels, and pixels are connected to form extended 8-connectivity seams, with each seam having a cumulative energy value. The digital image is segmented into segments corresponding to lines of text and/or images. A seam is selected to best maintain proportionality of white space in the segments when the seam is either replicated or deleted. The selected seam then replicated or deleted. At least the seam selection and replication or deletion is repeated until the resized image is the desired size. The resized image is then outputted to a display screen, storage device, and/or printer.Type: GrantFiled: October 6, 2008Date of Patent: January 10, 2012Assignee: Xerox CorporationInventors: Edgar Bernal, Robert P Loce

Publication number: 20120005225Abstract: A method and a system are disclosed for querying a document collection based on the layout of only a fragment of the content of a document, specified as a query zone. The method includes providing an index for a collection of documents. In the index, content of a document page in the collection that has been decomposed into layout blocks is indexed according to representations of the blocks and one or more geometric relations between the blocks. A query is generated which is based on representations of blocks determined to be within the query zone and geometric relations between them. This is used to query the index to retrieve pages of documents in the collection which can each be expected to include a layout zone somewhere in the page that is similar in layout to the query zone.Type: ApplicationFiled: July 2, 2010Publication date: January 5, 2012Applicant: Xerox CorporationInventor: Boris Chidlovskii
