Method and apparatus for compressive acquisition and recovery of dynamic imagery
A new framework for video compressed sensing models the evolution of the image frames of a video sequence as a linear dynamical system (LDS). This reduces the video recovery problem to first estimating the model parameters of the LDS from compressive measurements, from which the image frames are then reconstructed. We exploit the low-dimensional dynamic parameters (state sequence) and high-dimensional static parameters (observation matrix) of the LDS to devise a novel compressive measurement strategy that measures only the dynamic part of the scene at each instant and accumulates measurements over time to estimate the static parameters. This enables us to lower the compressive measurement rate considerably yet obtain video recovery at a high frame rate that is in fact inversely proportional to the length of the video sequence. This property makes our framework well-suited for high-speed video capture and other applications. We validate our approach with a range of experiments including classification experiments that highlight the purposive nature of our framework. |

Systems and methods for testing network connections of a centrally-controlled network
A computer network testing process to determine whether, given a network node that is unreachable by communication attempts from a controller on a control-plane network, the network node is still functioning to forward data packets on a data-plane network, or if the network node is fully non-functional on both the control-plane network and data-plane network. In order to make this determination, the testing process identifies a network node that is still reachable by the controller on the control-plane network, identifies a route between the controller and unreachable node, passing through the reachable node, and constructs an encapsulated test packet that is sent along this route. In response to sending the encapsulated test packet, the controller may, upon receipt of a confirmation packet, determine that the unreachable node is still functional on the data-plane network, or if no confirmation packet is received, mark the unreachable node as fully non-functional. |
