Processing and system for effective detection of events in a large number of concurrent image sequences.

摘要

Procedure for use in realizacióProcedimiento for use in performing event detection and tracking objetosn event detection and object tracking in image streams, using a system, is in image streams, using a system, is formed through a series of devices I adquiá formed by a number of image acquisition devices, each installed in camposición images, each installed in field where it has detected an event and connected au where be detected an event and connected a central station through a data network, na central station through a data network, the method comprising: processing a formatcomprendiendo procedure: processing a digital format of an image stream, consisting digital ene flow image, consisting of one or more images, to detect features one or more images, for detect features, being parameters related to attributes which are parameters related to attributes of objects in said image stream, and, bas of objects in said image stream, and, based on these features, performing deteccisado in these features, performing the event detection and object tracking, ng events and tracking objects, the method being characterized by the fact the method being characterized by the fact that: each of the acquisition devices that: each image acquisition devices is preprogrammed to work with images is pre-programmed to work with a server image processing such estservidor image processing at said central station on the basis of distribution center algación on the basis distribution of image processing algorithms between eldispoori tmos image processing between dispsitivo image acquisition and server eositivo image acquisition and the server, stando controlled acquisition device deestando controlled device acquisition d images by the server to apply a exe images by the server to apply a etracción of low-level features to formaxtracción of low-level features to digital formto image stream, comprising digital diate image stream, comprising Right feature extraction under elicha level extracting low level features and analysis a frame and identifying dichol analysis frame and identifying dich frame as an event generating, from said frame as an event generating, from doctor image flow, flow cho characteristics image stream , flow characteristics that sea orrespondiente co, and transmission corresponding to said frame, and transmission dedicho flow characteristics server proc said feature stream to the server proesamiento image through the data network, cessing image through the data network provided that the characteristics exceed a limit, provided that the features exceed a corresponding limit, corresponding determined dynamically me, hrough determined dynamically said processing server imágenemediante said IMAGENS processing server; whereby the flow characteristics Indicates; whereby the flow indicaivo characteristics frame identified as containing posibtivo frame identified as containing posilemente an event is configured for procesamienblemente an event is configured for further procesamieto high level by said additional servidornto high level by said served image processing, thus making lr image processing in order to perform a event detection and tracking objetola event detection and tracking objet flow indicative characteristics of said flow indicative characteristics Physicians image streams. hos image streams.
