Title: Image data encoding and decoding
Inventor: STEPHEN MARK KEATING
IPC: H04N19/593
Filed: 2017-10-27
Abstract: Image encoding and decoding of a current region 2050 of a current image, the region being an array of two or more rows and two or more columns of samples. One of a set of candidate prediction operations is selected for predicting the samples, each operation defining at least a prediction direction 2060. An intra-image predictor derives the predicted samples of the current region using one or more of a group of reference samples dependent on the prediction direction, where for a current sample 2065, the group of reference samples are between the current sample and a reference position 2090 & 2095 amongst the reference samples. The group of reference samples comprise at least two parallel linear arrays 2070 & 2075 of reference samples at different respective separations form the current region. The predicted sample may be derived by combining or interpolating the reference samples. A weighted combination may be used wherein the weighting decreases as distance from the current region increases.

IPC: G01K13/00
Filed: 2018-01-18
Abstract: The invention relates to vehicle sensor health monitoring. A processor of a road-side station may receive first data from a vehicle 310 and receive second data from sensors associated with the road-side station 320. The processor compares the first data and the second data 330. In response to a result of the comparing indicating a difference between the first data and the second data, the processor generates a report 340, diagnosing the health of the sensors. This may indicate inaccuracy or anomalies present in the sensors. The data may relate to positioning, weather, error detection etc. The report has a health score which may be broadcast to other vehicles or a remote location 350, 360. Health reports from other vehicle may be received 370. The data may be transmitted wirelessly using V2X communication. This allows malfunction in the sensors of an autonomous vehicle to be detected.

Title: Force-directed graph layout
Inventor: GRAHAM WADDINGHAM
IPC: G06F17/17
Filed: 2020-03-30
Abstract: A method for generating a force-directed graph having vertices (nodes, 310(1)- (6)) and edges connecting the nodes. The graph layout is a result of the force exerted by each node on every other node. The method generates an initial layout of the nodes and determines an effect of global interactions based on the force between the nodes by grouping the nodes based on their initial location, determining an aggregate effect on each group of nodes, determining from each node a local interaction based on the force with the most proximate nodes (local area 610), and applying an adjustment to the location of each node based on the combined effects of global and local interactions. The vertices may be grouped based on their location as defined by a grid. The method may be performed iteratively until an equilibrium is reached. The forces may be repulsive or attractive and follow a physical model (e.g. Coulomb's law, Hooke's law etc).
