摘要： Techniques are disclosed for detecting foreground objects in a scene captured by a surveillance system and tracking the detected foreground objects from frame to frame in real time. A motion flow field is used to validate foreground object(s) that are extracted from the background model of a scene. Spurious foreground objects are filtered before the foreground objects are provided to the tracking stage. The motion flow field is also used by the tracking stage to improve the performance of the tracking as needed for real time surveillance applications.

摘要： Techniques are disclosed for matching a current background scene of an image received by a surveillance system with a gallery of scene presets that each represent a previously captured background scene. A quadtree decomposition analysis is used to improve the robustness of the matching operation when the scene lighting changes (including portions containing over-saturation/under-saturation) or a portion of the content changes. The current background scene is processed to generate a quadtree decomposition including a plurality of window portions. Each of the window portions is processed to generate a plurality of phase spectra. The phase spectra are then projected onto a corresponding plurality of scene preset image matrices of one or more scene preset. When a match between the current background scene and one of the scene presets is identified, the matched scene preset is updated. Otherwise a new scene preset is created based on the current background scene.

摘要： A method of transmission between network equipment and user equipment, a method of network equipment transmission, a method of user equipment reception, a network equipment, an user equipment and a telecommunications system are disclosed. Packets transmitted over a channel containing information elements are multiplexed in accordance with a predetermined format in which each information element has an identifier which identifies that information element within that packet. The method comprises the steps of: determining that a packet to be transmitted over the channel will not contain more than one information element; transmitting an indicator between the network equipment and the user equipment to indicate that the packet to be transmitted over the channel will be encoded with a revised format in which no identifiers are provided; transmitting a packet over the channel encoded with the revised format with any identifiers omitted; and decoding the packet received over the data channel in accordance with the revised format to extract the information element.

摘要： A machine-learning engine is disclosed that is configured to recognize and learn behaviors, as well as to identify and distinguish between normal and abnormal behavior within a scene, by analyzing movements and/or activities (or absence of such) over time. The machine-learning engine may be configured to evaluate a sequence of primitive events and associated kinematic data generated for an object depicted in a sequence of video frames and a related vector representation. The vector representation is generated from a primitive event symbol stream and a phase space symbol stream, and the streams describe actions of the objects depicted in the sequence of video frames.
