摘要： What is disclosed is a resizing method that utilizes segmentation information to classify objects found within a document and then selects the most appropriate resizing technique for each identified object. The present method employs readily available document parsers to reliably extract objects. e.g. text, background, images, graphics, etc., which compose the document. Information obtained from a document parser is utilized to identify the document components for classification. The extracted objects are then classified according to their object type. Each of classified objects are then resized using a resizing technique having been pre-selected for the object type based on their respective abilities to resize certain types of document content over other resizing techniques. The present method advantageously extends smart or content-based scaling and is especially useful for N-up or variable-information printing. The present method finds its intended uses in enhancing N-up and handout options currently provided in a variety of print-drivers.

摘要： In various exemplary embodiments, systems include a segmentor to segment text binary image data to a first plane. A subtractor subtracts text binary image from binary image data to generate a non-text binary image data in a second plane. A converter converts non-text binary image data in the second plane into non-text gray scale image data in the second plane. A first compressor compresses the text gray scale image data in the first plane. A second compressor compresses the non-text gray scale image in the second plane.

摘要： Present systems and methods provide for adaptive job-size prediction that can enable the user of a scan-to-export function to obtain continuing feedback as original documents are being scanned, regarding the transferability of a scanned and processed data file. The compression method that is selected to process a scanned image is used to predict the output size for the associated data and to provide an estimated size for the job. The estimated size of the data being prepared for output is compared to the amount of storage space that is available at the target device and if the estimate exceeds available space, a signal is generated to terminate the scan or take other appropriate action. The user is also immediately notified if the transfer will fail for other reasons, such as the entry of an invalid target destination address or invalid user authentication.

摘要： A system and method of billing for scanning service costs is provided to examine content of a page and apply a cost function to approximate the cost of scanning the page. Examining the page includes detecting an object in the page, determining a type of the detected object, determining an approximate file size of the page, and determining an approximate area of coverage of the detected object within the page. A usage profile of each type of detected object is calculated and stored. The cost function uses the detected object, the approximate file size, the approximate area of coverage, and a weight value associated with the type of detected object to approximate the cost of the page. When costs are calculated over a period of time, the weight value of each type of detected object may be adjusted based on the usage profile for each type of detected object.

摘要： In one embodiment, a method for setting up a flow-through mesh group (FTMG) for transmitting link-state packets (LSPs) in a network having a plurality of nodes interconnected by links. The FTMG is a combination of multiple spanning trees for the network through which LSPs are forwarded. FTMG set-up messages are received at ports of each node of the network from peer ports of linked nodes. FTMG set-up messages identify root nodes of the multiple spanning trees and the transmission modes of the peer ports. The FTMG set-up messages are used to determine (1) a root node for each spanning tree, (2) a root port on each node for each spanning tree, and (3) directionality of ports of the nodes. FTMG set-up messages are then used to determine the transmission mode of ports of the nodes and, subsequently, to update the spanning trees and transmission modes, as needed.

摘要： What is disclosed is a system and method for performing a background deletion that exploits both local and global context to remove background and other white space between objects with the aim of retaining structural relationships between objects in the document. A document image is received and seams are carved through the image. Seams composed of uniform background pixels are identified. Adjacent seams containing background pixels are collected into groups of seams. The background seam groups are classified according to their widths. A target number of seams to be removed for each background seam group is then determined based on the classification. Seam groups which are wider will have at least the same or a greater target number of seams to be deleted therefrom than will seam groups of narrower widths. The document image is then resized by deleting seams from the seam groups based on the assigned target number.

摘要： A technique for improving optical cross-connections comprises placing a switch in front of a number of processing units. So configured, the units are no longer dedicated to a specific link or signal. When necessary, a unit is connected/disconnected to one or more optical links by the switch to carry out any number of processing functions, such as regeneration, Raman pumping, dispersion equalization/compensation or performance monitoring. Because the units are no longer dedicated to specific links the cost of the cross-connections and the network it is a part of can be reduced.
