摘要： A method for associating text with image data of documents is herein described. The method includes receiving image data of a document with manually marked text and recognizing the manually marked text. The image data is then annotated (e.g., tagged) using the manually marked text and the image data of the document is stored. When manually marked text is recognized, recognized text may be generated for annotating the image data of the document and used to populate a field associated with the image data. The field may be a name of the document or a subject line of an e-mail message, for example. A method including identifying the location of manually marked text in a first scanned document to automatically identify and annotate text in a corresponding location in a second scanned document is also disclosed.

摘要： Training sets consisting of pairs of input images and desired images can be used to produce maps intended for future use in transforming input images into final images. The maps, however, often have improper elements based on incomplete or noisy data. The noisy data and incomplete can be identified via statistics derived from the training set. The map can output a code value instead of a substitution for an improper element. An additional stage of image transformation can identify improper pixels having the code value and replace the code value with an analytic value that is more appropriate.

摘要： The present invention provides a method and apparatus for routing a data flow from a source node to a destination node in a mobile ad-hoc network (MANET). The present invention performs this function by first determining desired service requirements for an individual data flow to be forwarded to a destination node. Next, the present invention broadcasts an advertisement for each of the links in the MANET by the corresponding origination nodes, the advertisement including a value indicating the current performance level of the link. After broadcasting the advertisements, routing tables are composed at each of the nodes based upon the advertisements. Each routing table is constructed taking into account the advertised links and their corresponding values. After composing the routing tables, packets are forwarded toward their respective destinations by utilizing the routing tables in such a manner that the desired service requirements are satisfied.

摘要： Traffic demands are routed between network elements so as to provide improved protection against network failures. A given traffic demand is routed from a first network element to a second network element, where the second network element is preferably either one of a set of dual-homed elements, or coupled to a dual-homed element, and may also be an element of a ring-type transport or a mesh-type transport. The second network element processes the traffic demand such that a copy of a signal associated with the demand is (i) retained at the second network element, while the signal is routed to at least one additional network element, or (ii) routed to at least one additional network element, while the signal is routed to at least one network element other than the additional network element. For example, in a multidrop connection implemented in accordance with the invention, a copy of the signal is “dropped” at the second network element and one or more additional network elements. In a multicast connection implemented in accordance with the invention, one or more copies of the signal are multicast from the second network element to multiple additional network elements.

摘要： Present systems and methods enable user-defined image processing parameters to be applied as intended in some regions of a scanned image without applying them in other regions. More specifically, present systems and methods enable a digital reproduction system to automatically adjust for any inherent interactions between separate image processing modules. Present systems and methods need not be concerned about color adjustments that are made by user-defined settings since the system would automatically adjust for interactions between user-defined settings and automatic adjustments that are made by the system. Present systems and methods provide the flexibility that would be obtained by re-arranging the imaging modules in the processing path of an image processing system.

摘要： In a machine-fed scanner, orientation angles of edges of an image bearing substrate are obtained and used to calculate image shear and/or skew. A running weighted average of the image skew may be kept in a memory. When a skew value is obtained for a given image, it may be determined whether the skew value is within a predetermined range. If the skew value is within the predetermined range, the skew value is used to determine an image revision to compensate for the skew, and the skew value is incorporated into the running weighted average skew. If the skew value is not within the predetermined range, it is discarded and the running weighted average skew is used to determine an appropriate image skew revision. The running weighted average of the shear may also be kept in a memory. A shear value is obtained for each image, and incorporated into the running weighted average shear. Shear revision is performed based on the running weighted average shear. A determination may be made whether the shear value for a current image is within a predetermined range, and the running weighted average shear may be updated based on the shear value for the current image if the shear value for the current image is within the predetermined range.

摘要： Units of traffic are routed between nodes in a network on corresponding sets of trunks, such that the traffic is balanced between disjoint paths. A restoration process for the traffic is implemented using service layer or transport layer switching. In a first embodiment, first and second nodes are connected by first and second sets of trunks, with each of the trunks in a given set of trunks supporting a designated portion of a given one of the units of traffic. The units of traffic are then routed such that a first half of a given one of the units of traffic is routed on a first one of the trunks in a given one of the sets of trunks, and a second half of the given unit is routed on a second one of the trunks in the given set of trunks. In other embodiments, the first and second nodes are connected by first and second sets of trunks so as to form a four-trunk ring, with each of the first and second sets of trunks including a primary trunk and a backup trunk. A given one of the units of traffic is then routed on either an upper or lower portion of the ring. The four trunk ring may be in the form of an IP/optical hybrid ring, in which case the restoration process is implemented using service layer switching, or a SONET/optical ring, in which case the restoration process is implemented using transport layer switching.
