Method and device for coding and decoding motion vector
ActiveCN101860754AFast codec processingHandling of reliable codecsTelevision systemsDigital video signal modificationTemplate matchingMotion vector
The present invention relates to a video coding method. Specifically, the invention relates to motion vector (MV) coding, wherein the MV coding is based on edge matching or adaptive template matching, namely the motion vector coding based on boundary matching (MVCBM) and the motion vector coding based on adaptive template matching (MVCATM). Generally speaking, the invention limits a prediction candidate set, wherein a predictor adaptively changes based on the current distribution of the adjacent MV. Subsequently, a matching technique (boundary matching in MVCBM and adaptive template matching in MVCATM) is used for reducing the number of the prediction and reducing the number of bits used by indexing. Afterwards, an optimal motion vector predicator is selected from the reduced concentrated predictor. The guessing strategy based on the least MVD standard further saves the number of indexing bits.

Apparatus and method for managing internet resource requests
InactiveUS7343399B2To offer comfortMultiple digital computer combinationsElectric digital data processingTraffic capacityEdge based
DNS in its native form cannot identify a good or best server. Traditional Service Providers deploy a centralised approach to global traffic management based on enhancements to DNS, but do have the capability to augment this with edge-based server selection because they do not own / operate an edge network. Their resolution of DNS requests is typically restricted to identifying candidate servers within an edge domain rather than selecting the “best” server. The invention proposes a method of handling Internet resource requests whereby a local lookup server receiving a request searches for a best server able to satisfy the resource request. The local lookup server finds the best server by searching a database for a resource record associated with the best server, and then uses the resource record to retrieve an identifier of a series of executable instructions that are executed to locate the best server. The resource requests and responses may hold additional information relating to operational characteristics which may used to determine the best server. The invention proposes a DNS record type comprising a user-defined field for conveying this additional information in the resource request and in the response. The invention also proposes architecture for handling the resource request comprising a network server that provides the requested resource using the best server, as well as a communications network comprising this architecture.

Inferring file and website reputations by belief propagation leveraging machine reputation
The probability of a computer file being malware is inferred by iteratively propagating domain knowledge among computer files, related clients, and / or related source domains. A graph is generated to include machine nodes representing clients, file nodes representing files residing on the clients, and optionally domain nodes representing source domains hosting the files. The graph also includes edges connecting the machine nodes with the related file nodes, and optionally edges connecting the domain nodes with the related file nodes. Priors and edge potentials are set for the nodes and the edges based on related domain knowledge. The domain knowledge is iteratively propagated and aggregated among the connected nodes through exchanging messages among the connected nodes. The iteration process ends when a stopping criterion is met. The classification and associated marginal probability for each file node are calculated based on the priors, the received messages, and the edge potentials associated with the edges through which the messages were received.

Displacing edge segments on a fabrication layout based on proximity effects model amplitudes for correcting proximity effects
InactiveUS6665856B1Photomechanical exposure apparatusMicrolithography exposure apparatusEdge segmentEdge based
Techniques for forming a fabrication layout, such as a mask, for a physical design layout, such as a layout for an integrated circuit, include correcting the fabrication layout for proximity effects using a proximity effects model. A proximity effects model is executed to produce an initial output. The initial output is based on a first position for a segment in a fabrication layout. The first position is displaced from a corresponding original edge in the original fabrication layout by a distance equal to an initial bias. The model is also executed to produce a second output based on a second position for the segment. The second position is displaced from the corresponding original edge by a distance equal to a second bias. An optimal bias for the segment is determined based on the initial output and the second output. The segment is displaced in the fabrication layout from the corresponding edge based on the optimal bias.

An efficient and non-iterative 3D post processing method and system is proposed for mosquito noise reduction, block localization and correction in DCT block-based decoded images. The 3D post processing is based on a simple classification that segments a picture in multiple regions such as Edge, Near Edge, Flat, Near Flat and Texture regions. The proposed technique comprises also an efficient and shape adaptive local power estimation for equivalent additive noise and provides simple noise power weighting for each above cited region. Temporal filtering configurations using Minimum Noise Variance Criterion are proposed for reducing temporally varying coding artifacts. A Minimum Mean Square Error or Minimum Mean Square Error-like noise reduction with robust and effective shape adaptive windowing is utilized for smoothing mosquito and / or random noise for the whole image, particularly for Edge regions. The proposed technique comprises also signal domain histogram analysis based Block Localization and adaptive edge based Block artifact correction. Finally, is also proposed an optional adaptive detail enhancer which can enhances the luminance signal in eight directions differently.

ActiveUS20060077918A1Efficient routingReliable data transmissionEnergy efficient ICTElectric signal transmission systemsLine sensorDirectional antenna
A scalable, minimum node complexity, energy efficient, and error-resilient routing method for wireless sensor networks is described. The network is partitioned into regions by power controlled base station scans using a directional antenna. Routing is performed using only local location information and instructions received from the base station at each sensor node with minimum processing and control overhead, thus allowing simple, low-cost sensor designs. Sensors in the network provide to a base station reports of the condition of the sensors themselves, and these reports are analyzed by the base station to determine improved routing instructions, which are then provided to the sensor nodes in control messages. Each data packet is relayed in an interleaved, loop-free mesh of sectors toward the base station, making data delivery robust to sensor failures and transmission errors. The disclosure also contains descriptions for simple edge-based tasking, query, code distribution, and network programming for sensor nodes. The method is suitable for large-scale, dense sensor networks for detection, alarming, and monitoring applications.

Deinterlacing of video sources via image feature edge detection
ActiveUS7023487B1Reduce artifactsPreserves maximum amount of vertical detailImage enhancementTelevision system detailsInterlaced videoProgressive scan
An interlaced to progressive scan video converter which identifies object edges and directions, and calculates new pixel values based on the edge information. Source image data from a single video field is analyzed to detect object edges and the orientation of those edges. A 2-dimensional array of image elements surrounding each pixel location in the field is high-pass filtered along a number of different rotational vectors, and a null or minimum in the set of filtered data indicates a candidate object edge as well as the direction of that edge. A 2-dimensional array of edge candidates surrounding each pixel location is characterized to invalidate false edges by determining the number of similar and dissimilar edge orientations in the array, and then disqualifying locations which have too many dissimilar or too few similar surrounding edge candidates. The surviving edge candidates are then passed through multiple low-pass and smoothing filters to remove edge detection irregularities and spurious detections, yielding a final edge detection value for each source image pixel location. For pixel locations with a valid edge detection, new pixel data for the progressive output image is calculated by interpolating from source image pixels which are located along the detected edge orientation.

The ensuring of predictable and quantifiable networking performance. Embodiments of the invention combine a congestion free network core with a hypervisor based (i.e., edge-based) throttling design to help insure quantitative and invariable subscription bandwidth rates. A lightweight shim layer in a hypervisor can adaptively throttle the rate of VM-to-VM traffic flow. A receiving hypervisor can detect congestion and communicate back to sending hypervisors that rates are to be regulated. In response, sending hypervisors can reduce transmission rate to mitigate congestion at the receiving hypervisor. In some embodiments, the principles are extended to any message processors communicating over a congestion free network.
