A method of managing a computer network in a production environment is described. The method comprises:

Controller, computer program and method

A method of calculating a new route for a media data traffic flow on a computer network when a device is connected to the network, the network comprising a first and a second network switch connected by a link, the method comprising: determining whether media data traffic already flows between the first and second network switch over the link; applying a weighting to the link whose value is based on whether media data traffic already flows over the link; and determining the new route for media data traffic by using a least cost path generation algorithm using the weighting.

Controller, computer program and method for calculating host specific network paths

A packet-based software-defined data network supporting multicast, unicast and/or broadcast packet-based data traffic types comprises a software defined network (SDN) controller; and a network of one or more packet switches arranged to route, under the control of the SDN controller, data packets from one or more packet sources to one or more packet receivers, in which the SDN controller is responsive to data defining a topology of interconnections between the plurality of packet switches, packet sources, and packet receivers, to select a route for packets from a packet source to a packet receiver; the SDN controller being configured to select the route in dependence upon the traffic type of the packets to be routed, using a respective one of a set of route selection algorithms each applicable to one of multicast, unicast and broadcast packet-based data traffic types.

Data network

An image analysis apparatus for processing a 3D video signal comprising successive pairs of images representing different respective views of a scene to generate an image depth indicator comprises a correlator configured to correlate image areas in one of the pair of images with image areas in the other of the pair of images so as to detect displacements of corresponding image areas between the two images; a graphics generator configured to generate a graphical representation of the distribution of the displacements, with respect to a range of possible displacement values, across the pair of images; and a display generator for generating for display the graphical representation in respect of a current pair of images and in respect of a plurality of preceding pairs of images, so as to provide a time-based representation of variations in the distribution of the displacements.

Analysis of 3D video

A method of determining the amount of mis-alignment in one direction of an image of a scene, the image captured by a first camera is described. The method comprising the steps of:

Method and apparatus for determining the mis-alignment in images

A first image captured by a first camera can be aligned with at least a segment of a second image captured with a second camera, where the images have an overlapping field of view. Image characteristic values indicative of image characteristics at positions within the overlapping field of view of the first and second images are respectively determined. A difference in position between corresponding image characteristic values in the overlapping field of view in the first image and the overlapping field of view in the second image is determined. A transform is applied to the first image, adjusting an orientation of the first image relative to the second image. The first and second image can be aligned when the difference in position between corresponding image characteristic values in the first and second image is a predetermined amount.

Method and apparatus for image alignment

Video signals which represent a scene as viewed by a camera are processed to combine a computer generated object with the video signals with the effect that the computer generated object appears within the scene when the video signals are displayed. The scene includes a first object. The process includes mapping a virtual model of the first object to a position of the first object within the scene so that the virtual model substantially corresponds with the real object. The virtual model has a degree of transparency such that the virtual model can be rendered as a substantially transparent virtual object within the scene. The process further includes detecting occluded regions of the virtual model. The occluded regions correspond to regions of the virtual model which are hidden from a virtual light source by the computer generated object. The process also includes modifying the degree of transparency of the virtual model at the occluded regions so as to generate modified transparency regions, and rendering the scene in combination with the computer generated object and the virtual model such that the modified transparency regions of the virtual model appear as shadows on the first object.
