摘要： In one embodiment, an automatically maintained, distributed source tree (DST) network has a plurality of fully connected internal nodes. One or more internal nodes may be connected to one or more external nodes. A first internal node synchronizes its link-state database with another internal node by sending and receiving respective Reduced Sequence Number Packet-Data-Units (PDUs) (RSNPs). An RSNP includes summary information for link-state packets (LSPs) (1) originated by the first internal node, (2) received by the first internal node from the other internal node, and (3) received from and/or originated by external nodes. If an internal link fails, then the corresponding end-nodes may recover and maintain automatic DST operation by entering either relay-mode or switch-mode operation. In relay-mode operation, an end-node tunnels packets to the other end-node via an intermediary node. In switch-mode operation, an intermediary node is selected to forward packets from one end-node to the other end-node.

摘要： A method and system reconstructs a contone image from a binary image by first tagging pixels to identify one of a multiplicity of image content types. The tag information and the pattern of bits surrounding the pixel to be converted to a contone value are used to reconstruct a contone image from a binary image. The pattern of bits in the neighborhood is used to generate a unique identifier. The unique identifier is used as the address for a lookup table with the contone value to be used wherein each lookup table corresponds to an image context type.

摘要： The disclosed systems and methods pertain to the processing of large format images in a manner to avoid introducing imaging defects, and more particularly to dividing the large image into bands, processing these bands in parallel and then putting them back together in to create the final processed image. The methods include the use of overlapping the image bands, padding of the bands prior to processing and the redefinition of image values at common boundaries of the bands to minimize or eliminate visible defects.

摘要： A method of determining a quality of a file of a scanned page based upon a user selected input including examining the content of the scanned page via detecting at least one object on the scanned page, classifying each object on the scanned page and estimating a file size of each object on the scanned page. A file size of the scanned page is approximated based upon the estimated file size of each object on the scanned page. A user input for the scanned page is received and compared to the approximated file size of the scanned page. Finally, a file is generated from the scanned page wherein the quality of the file is based upon the comparison between the user selected input and the approximated file size of the scanned page.

摘要： A method is described to match an original binary image with the dynamic range of a desired target document. The original binary image is restored first to contone and a histogram of the contone image is processed to generate a Tone Reproduction Curve (TRC) for the contone image with improved dynamic range. The histogram processing includes determining a histogram of the contone image, and generating the TRC based on matching the determined histogram with a target histogram profile. This helps in matching outputs from legacy devices to a desired quality.

摘要： In a packet-based data network, packets are duplicated and a sequence number is inserted into each duplicate packet, where the duplicate packets are transmitted along two different paths from a source node to a destination node in the network. Depending on the implementation, the source node inserts different types of sequence numbers into the duplicate packets, and the destination node processes those sequence numbers accordingly to determine whether to accept or reject each received packet. In certain implementations, the number of sequence bits allocated to each packet is smaller than the size of the effective sequence number for the packet as interpreted by the destination node.
摘要翻译： 在基于分组的数据网络中，分组被复制，并且将序列号插入到每个重复分组中，其中重复分组沿着从源节点到网络中的目的地节点的两个不同路径传输。 根据实现，源节点将不同类型的序列号插入到重复分组中，并且目的节点相应地处理这些序列号，以确定是接受还是拒绝每个接收到的分组。 在某些实现中，分配给每个分组的序列比特数小于由目的地节点解释的分组的有效序列号的大小。

摘要： Multiple requests to set up and/or tear down connections in a node of a communication network (or multiple failure notifications) are bundled together for transmission within the network. In an “inter-nodal” embodiment, multiple connection requests/failure notifications are bundled together as a single message for transmission between pairs of nodes in the network. In an “intra-nodal” embodiment, multiple connection requests/failure notifications received at one component of a node in the network are bundled together as a single group for forwarding to another component within the same node for implementation. In either case, the bundling of multiple connection requests/failure notifications can reduce the total amount of time required to communicate and implement the desired connection requests/restoration processing. This reduction in time can be critical to the ability of a network to satisfy requirements associated with restoration processing following a network fault.
