Abstract: A system for preparing a first multimedia stream, for use with an environment comprising a repository for storing a plurality of tracks, wherein each track is associated with at least one second multimedia stream. A track comprises a single type of data (e.g. audio, video etc.). The system comprises means for receiving a request comprising an associated parameter (e.g. position parameter); means for determining at least two of the plurality of tracks associated with the parameter (e.g. wherein the at least two tracks have associated information that matches the position parameter); and means, responsive to the determining means, for collating the determined at least two tracks in order to generate the first multimedia stream.

Abstract: A monitoring system using two or more cameras to monitor a space in 3 dimensions is disclosed. One or more virtual 3-D monitored volumes relating to dangerous or restricted areas, are constructed, preferably as CSG objects, within this space. By detecting an object moving within the view of the cameras, the system can determine if a moving object intersects any monitored volumes and take appropriate action.

Abstract: The invention relates to a method for reducing the computational overhead of bicubic interpolation while still providing a similar level of accuracy. The invention takes into account the fact that sampled points surrounding a point whose value is to be determined have respective first, second and third order effects on the calculated value. The invention combines linear interpolation, ignoring points having a third order effect, with cubic interpolation of points having a first and second order effect to derive the value.

Abstract: A reticle for an object measurement system comprises a pattern 10 having a plurality of pairs of contrasting elements in the form of black (11′, 11″ . . . 14′14″) and white (21 . . . 24) wedges. Each black/white wedge pair defines a path towards a pattern origin 19 such that an edge of an object 50 occluding the path causes a change in contrast adjacent an edge point along the path. The pattern has a series of Gray-coded elements 15 associated with each pair of black/white wedges. The Gray-coded elements are indicative of an absolute coordinate of each edge point at which an object edge crosses a path. A series of triangles 16 associated with each pair of black/white wedges, whose absolute coordinates are known, allow a measurement system to provide accurate coordinates for each edge point.
