    Abstract: A local object classifier using a set of object definitions to perform object classification in image frames. The local object classifier is arranged to detect an object in an image frame and determine whether to transmit image data for the detected object to a remote object classifier. In response to said determining, the local object classifier is arranged to transmit image data, derived from the image data representative of the image frame, to the remote object classifier. The local object classifier is also arranged to receive object data, representative of the detected object, from the remote object classifier.

    Abstract: In a graphics processing system, a bounding volume 20 representing the volume of a scene to be rendered and a cube texture 30 representing the transparency of the surface of the bounding volume are defined. Then, when the scene is to be rendered for output, a color to be used to represent a first sampling point 25 as seen from a viewpoint position 24 for the scene is determined by determining, for each of plural second sampling points 27 along a vector 26 from the first sampling point 25 to the viewpoint position 24, a transparency parameter indicative of the amount of light that falls on the second sampling point 27, and then using the determined transparency parameter values for each of the plural second sampling points 27 to determine the color. Each transparency parameter is determined by determining a vector 29 to be used to sample a graphics texture 30 that represents the transparency of the surface of the bounding volume 20 in the scene, and then using the determined vector 29 to sample the graphics texture 30 to determine the transparency parameter value for the light source 22 for the second sampling point 27.

    Abstract: A graphics processing system for generating a render output using an input curve defined in a world space includes processing circuitry configured to determine a portion of a canonical curve defined in canonical space that corresponds to the input curve and the transformation needed to map the input curve to the portion of the canonical curve. For sampling points in the world space surrounding the input curve, the processing circuitry is configured to transform the sampling points from the world space to the canonical space using the determined transformation between the world space and the canonical space; and determine, in the canonical space, the closest point on the determined portion of the canonical curve to the transformed sampling point. The system also includes processing circuitry capable of using the determined closest points on the canonical curve for the transformed sampling points in the canonical space when generating a render output.

    Abstract: A computer-implemented method for an augmented-reality system is provided. The computer-implemented method comprises obtaining sensed data, representing an environment in which the AR system is located, determining that the AR system is in a location associated with a first authority characteristic, and controlling access to the sensed data for one or more applications operating in the AR system. Each of the one or more applications is associated with a respective authority characteristic. Controlling access to the sensed data for a said application is performed in dependence on the first authority characteristic and a respective authority characteristic associated with the said application. An AR system comprising one or more sensors, storage for storing sensed data, one or more application modules, and one or more processors arranged to perform the computer-implemented method is provided. A non-transitory computer-readable storage medium comprising computer-readable instructions for performing the computer-implemented method is also provided.

    Abstract: A graphics processing system and method of operating a graphics processing system that generates “spacewarped” frames for display is disclosed. Motion vectors are used to determine the motion of objects appearing in rendered application frames. The so-determined motion is then used to generate “spacewarped” versions of the rendered application frames.
