In automatic assessment or surveillance with camera-based surveillance systems, it is of particular interest to detect moving surveillance objects, such as persons or motor vehicles, and track them over time so that if there are unusual trajectories or unusual behavior, an alarm can be tripped. An apparatus for image-based tracking of surveillance objects in front of a scene background in a surveillance scene is proposed, having an object segmentation module that is embodied for ascertaining moving object areas in front of the scene background on the basis of a comparison of one or more camera images with a reference image of the scene; having an administration module which is embodied for assigning surveillance objects to the moving object areas detecting fusion of two or more surveillance objects and marking them jointly as an object group; and having a feature detection module which is embodied in terms of programming and/or circuitry for determining local features for tracking the surveillance objects of the object group in the image areas defined by the moving object areas. |
