Picture coding supporting block partitioning and block merging
A further coding efficiency increase may be achieved if for a current block of a picture, for which the bit stream signals one of supported partitioning patterns, a reversal of the partitioning by block merging is avoided. In particular, if the signaled one of the supported partitioning patterns specifies a subdivision of the block into two or more further blocks, a removal of certain coding parameter candidates for all further blocks, except a first further block of the further blocks in a coding order, is performed. Particularly, those coding parameter candidates are removed from the set of coding parameter candidates for the respective further block, the coding parameters of which are the same as coding parameters associated with any of the further blocks which, when being merged with the respective further block, would result in one of the supported partitioning pattern. This avoids redundancy between partitioning coding and merging coding. |

Selection of motion vector precision
Approaches to selection of motion vector (“MV”) precision during video encoding are presented. These approaches can facilitate compression that is effective in terms of rate-distortion performance and/or computational efficiency. For example, a video encoder determines an MV precision for a unit of video from among multiple MV precisions, which include one or more fractional-sample MV precisions and integer-sample MV precision. The video encoder can identify a set of MV values having a fractional-sample MV precision, then select the MV precision for the unit based at least in part on prevalence of MV values (within the set) having a fractional part of zero. Or, the video encoder can perform rate-distortion analysis, where the rate-distortion analysis is biased towards the integer-sample MV precision. Or, the video encoder can collect information about the video and select the MV precision for the unit based at least in part on the collected information. |

Refinement of a low-pel resolution motion estimation vector
The refinement of a lower-pel resolution motion estimation vector is made more effective by preceding the actual refinement with a determination of a context out of a set of context candidates based on coding costs of a set of lower-pel resolution vectors within a neighborhood of the lower-pel resolution motion estimation vector, wherein each context candidate is associated with a ranking among a set of higher-pel resolution candidate vectors surrounding the lower-pel resolution motion estimation vector. The actual refinement of the lower-pel resolution motion estimation vector to obtain the higher-pel resolution motion estimation vector may thus use the ranking associated with the context determined: sequentially arranged accordingly, the set of higher-pel resolution candidate vectors may be tested sequentially. |

Boundary-intersection-based deblock filtering
A video encoder or video decoder buffers multiple blocks of a reconstructed picture of a video sequence. The video encoder/decoder performs deblock filtering between at least some of the multiple blocks. As part of the deblock filtering, the video encoder/decoder selectively filters at least some sample values in a diagonal line that crosses a block-boundary intersection between two diagonally adjacent blocks. When filtering sample values at the block-boundary intersection between four blocks, the video encoder/decoder can evaluate characteristics of all four blocks and adjust sample values in a line between diagonally adjacent blocks. If there is a large visual difference between sample values at corner positions of two diagonally adjacent blocks, the difference can be smoothed by filtering sample values in a diagonal line. In this way, the quality of motion-compensated prediction using the reconstructed picture is improved in many cases. |

Synchronized lighting and video active lighting tracks (VALT) with synchronized camera to enable multi-scheme motion picture capture
A method and system for synchronizing LED lighting to the shutters of fast digital cameras. The system enables capture of multiple lighting schemes to be filmed in a single video take on sequential frames. Since 24 frames per second is the industry standard used broadly in film and television, a 96 FPS camera can capture up to 4 lighting tracks of 24 FPS each in a single take. Each lighting fixture can be changed frame by frame to any desired intensity. The changing of lighting can be synchronized with the times when the shutter is closed so that all frames are complete and are without the visual artifact of the light changing mid frame. This is extremely useful for simple visual effects such as a simulated camera flash, lighting pattern or gun flash. The lighting can be programmed so that by turning on lights at the appropriate intensity while the camera shutters are closed all viewers on set perceive a constant, flicker-free light. The entire system is compatible with existing industry standards. |

Contact center routing mechanisms
Contact centers strive to match the best resource, commonly an agent, with a customer for an interaction, such as telephone call, text exchange, or email exchange. Often the initial best match is not the best match upon a different agent being identified and/or new information being gathered. Therefore, it is often beneficial to take a call routed to an agent, who may or may not have answered the call, and reroute it to a different agent. If the agent has already answered the call, the benefits need to at least exceed the costs associated with the transfer. To avoid creating an unstable or unending re-assessment, if the cost-benefit for a particular routing (or rerouting) calls between agents has reached a Nash Equilibrium, the system is stable and, absent new information, re-evaluation unnecessary. |

Detecting behavioral anomaly in machine learned rule sets
Roughly described, anomalous behavior of a machine-learned computer-implemented individual can be detected while operating in a production environment. A population of individuals is represented in a computer storage medium, each individual identifying actions to assert in dependence upon input data. As part of machine learning, the individuals are tested against samples of training data and the actions they assert are recorded in a behavior repository. The behavior of an individual is characterized from the observations recorded during training. In a production environment, the individuals are operated by applying production input data, and the production behavior of the individual is observed and compared to the behavior of the individual represented in the behavior repository. A determination is made from the comparison of whether the individual's production behavior during operation is anomalous. |

Method of separating the main part of a semiconductor substrate from the functional layer built on it
A process separates a main body of a semiconductor substrate from a functional layer. The method includes the steps of implanting ions into a semiconductor substrate through a top surface of the semiconductor substrate to form an ion damage layer underneath the top surface of the semiconductor substrate. After the ions are implanted into the semiconductor substrate, a functional layer is formed on the top surface of the semiconductor substrate. The main body of the semiconductor substrate is then separated from the functional layer. The method also includes forming the functional layer on the semiconductor substrate after ion implanting and then separating the functional layer from the main body of the substrate at the ion damage layer. This method avoids bonding in SOI and can thus reduce process steps and cost. |
