Patent number: 6574008Abstract: An image processing device that executes high speed overwriting of an input image with one or more partial images. A processing prediction unit judges whether overwriting is completed on all the partial images held in a small area buffer. If overwriting is completed, the overwritten partial image is compressed by an encoding unit, and the coded image is stored in a compact page memory. If overwriting is not completed, the uncompressed partial image is stored in the compact page memory. The uncompressed partial image is read from the compact page memory and is fed back to the overwriting unit through an output switch unit. The coded image stored in the compact page memory is sent to a decoding unit through the output switch unit, and is decoded to be outputted as an output image.Type: GrantFiled: February 28, 2000Date of Patent: June 3, 2003Assignee: Fuji Xerox Co., Ltd.Inventors: Taro Yokose, Ikken So, Mitsuyuki Tamatani, Yasuharu Sakurai

Publication number: 20030098983Abstract: In case of a “N-up” function, a correcting unit executes a correcting process operation with respect to an image read by an image input unit, a editing unit executes a magnification changing process operation, and thereafter, “N” sheets of images are placed side by side to form a single synthesized image at a time when the processed image is stored into a storage unit 15. When transmitting the synthesized image, an attribute of the image set from a U/I is added to the synthesized image and the control unit transmits the resulting image to an external apparatus. As a result, a reception side can execute an optimum processing operation with respect to the synthesized image with reference to the attribute added to the image. As a consequence, even in a “network copy”, the “N-up” function can be realized in a high image quality similar to that of a “direct copy”.Type: ApplicationFiled: October 18, 2002Publication date: May 29, 2003Applicant: FUJI XEROX CO., LTD.Inventor: Yoshihiro Terada

Publication number: 20030101187Abstract: Methods, systems, and articles of manufacture consistent with certain principles related to the present invention enable a computing system to perform hierarchical topical clustering of text data based on statistical modeling of co-occurrences of (document, word) pairs. The computing system may be configured to receive a collection of documents, each document including a plurality of words, and perform a modified deterministic annealing Expectation-Maximization (EM) process on the collection to produce a softly assigned hierarchy of nodes. The process may involve assigning documents and document fragments to multiple nodes in the hierarchy based on words included in the documents, such that a document may be assigned to any ancestor node included in the hierarchy, thus eliminating the hard assignment of documents in the hierarchy.Type: ApplicationFiled: October 19, 2001Publication date: May 29, 2003Applicant: Xerox CorporationInventors: Eric Gaussier, Francine Chen, Ashok Chhabedia Popat
