Residual error mitigation in multiview calibration
Multiview calibration is essential for accurate three-dimensional computation. However, multiview calibration can not be accurate enough because of the tolerances required in some of the intrinsic and extrinsic parameters that are associated with the calibration process, along with fundamental imperfections that are associated with the manufacturing and assembly process itself. As a result, residual error in calibration is left over, with no known methods to mitigate such errors. Residual error mitigation is presented in this work to address the shortcomings that are associated with calibration of multiview camera systems. Residual error mitigation may be performed inline with a given calibration approach, or may be presented as a secondary processing step that is more application specific. Residual error mitigation aims at modifying the original parameters that have been estimated during an initial calibration process. These new, modified parameters are then used for triangulation and depth estimation of scene information. This approach also resolves parameter tolerances that are either too cumbersome to measure, or otherwise impossible to measure for practical stereo and multiview camera production and calibration applications. |

Detecting static routes in a network
A detection mechanism is disclosed for identifying peers transmitting network traffic towards a cloud provider using routing prefixes that were not advertised for that peer. Once detected, an alarm condition can occur and the peer notified to remove any static route configurations. In one embodiment, a collector server computer can be used to acquire routing prefixes advertised to a peer. A second server computer can be used to obtain network traffic received from the peer. A comparison can then be made between the advertised prefixes and the network traffic being received. If network traffic is being received for unadvertised prefixes, then an alarm condition can occur. The detection mechanism can regularly inspect active traffic flows against BGP route advertisements at fixed intervals. For peers that are identified that are not in compliance with route advertisements, the alarm condition can occur for follow-up remediation. |

Disclosed are techniques for characterizing variants of interest and predicting assignments of individuals to communities based on obtained genetic information.

To determine if an individual belongs to a community, a subset of the individual's haplotypes are inputted into a community-specific model. The model is trained using the training samples that each include haplotypes of reference individuals and a label identifying whether the reference individual belongs to the community. Based on the output of the model, it is determined whether the individual is a member of the community. |
