Abstract: Methods and systems are disclosed for inferring address and subnet relationships. An exemplary method includes identifying a first address associated with a subnet; determining a length of a prefix part of the first address; determining a length of a prefix part of a second address; determining when a portion of the second address matches a portion of the first address; and determining when the lengths of the prefix parts of the first and second addresses are equal. A relationship between the second address and the subnet is inferred when the portion of the second address matches the portion of the first address and the lengths of the prefix parts of the first and second addresses are equal.

Abstract: Systems and methods that determine a path of a pen tip as the pen tip is moved across a document are described. The document is watermarked with a maze pattern from which encoded position information is determined. A sequence of images is captured by a camera that is located in a pen. The path of the pen tip is determined by decoding the associated maze pattern and by matching the captured images with document images. If the position coordinates of any frame that is associated with a stroke cannot be determined from m-array decoding, the frames are transformed and then matched with an area of a document image. Once the position coordinates of at least one frame is determined, the position coordinates of other frames are determined by matching the frames in a neighboring area.

The method further can include processing the circuit design through at least one other task of the CAD flow and outputting the processed circuit design.

Abstract: A computer network processes data packets in the event of a network link failure. The network includes a plurality of routers that deliver data packets to the network via a plurality of links. At least one router includes a protection cycle manager. The protection cycle manager has a protection cycle packet identifier and a protection cycle packet processor. The protection cycle packet identifier identifies, as protection cycle packets, data packets having a specific protection cycle format. The protection cycle packet processor processes protection cycle packets to determine whether the packet destination corresponds to the routing node, and if the packet destination corresponds to the routing node, the protection cycle packet is treated by the routing node as a data packet received from the packet source via the failed link. Otherwise, if the packet destination does not correspond to the routing node, the protection cycle packet is sent to a protection cycle node for the routing node.

Abstract: Systems and methods are described for real-time Bayesian 3D pose tracking. In one implementation, exemplary systems and methods formulate key-frame based differential pose tracking in a probabilistic graphical model. An exemplary system receives live captured video as input and tracks a video object's 3D pose in real-time based on the graphical model. An exemplary Bayesian inter-frame motion inference technique simultaneously performs online point matching and pose estimation. This provides robust pose tracking because the relative pose estimate for a current frame is simultaneously estimated from two independent sources, from a key-frame pool and from the video frame preceding the current frame. Then, an exemplary online Bayesian frame fusion technique infers the current pose from the two independent sources, providing stable and drift-free tracking, even during agile motion, occlusion, scale change, and drastic illumination change of the tracked object.

Abstract: A method that enables multiple spam detection solutions to be deployed in a manageable and rational manner to determine if a message is spam is presented. A framework invokes anti-spam filters to analyze the message and return confidence levels of whether a message is spam. The framework evaluates the highest confidence level against a set of defined thresholds. If the highest confidence level is greater than the highest threshold set by the administrator, the action specified for the highest threshold is taken. The highest confidence level is also compared against all thresholds and the action associated with the nearest threshold that has been exceeded is taken.

Global metadata may be decoded from the combined m-array by determining the respective amounts by which the plurality of copies of the first m-array are shifted, relative to the first m-array, in the combined m-array and by combining the respective amounts to produce a decoded value of the global metadata.

Abstract: A technique is disclosed for determining a portion of a document corresponding to a captured image. A user employs a pen to create a stroke in a document, and images are captured by a camera mounted on the pen. The locations of some of the images are determined by, e.g., analyzing a pattern on the document captured by the image or by a pixel-by-pixel comparison of the image with the document. The locations of other images are determined by segmenting the sequence of images into groups corresponding to the shape of the stroke. Information relating to a located image in a segment is employed to determine the position of an unlocated image in the segment. This determined position is used for obtaining further information that may be used to determine the position of another unlocated image in the segment, and so on, until the segment is finished.

Abstract: A method and system for decoding data on a medium that is captured by an input device is described. The method decodes a symbol design, such as an embedded interaction code (EIC), on a display screen, such as a liquid crystal display (LCD). An image that is captured by an input device, such as a universal pen-type input device with a camera, is received. The captured image is processed to output an extracted bit stream. Position data and/or metadata information is decoded from the extracted bit stream and a position of the captured image with respect to a screen of the LCD is determined based upon the decoded position data. The EIC pattern may be recognized from LCD pixel grids and a bit stream of EIC bits may be extracted based upon the recognized EIC pattern.
