1. A method for detection and/or tracking of objects in motion ( 16 ) in a scene under surveillance ( 15 ), in which besides the objects in motion ( 16 ), interfering objects and/or interfering regions—both hereinafter called interfering factors ( 17 , 23 )—can occur, in which the scene under surveillance ( 15 ), a plurality of regions are defined that are divided up into various region classes; and a first region class (D 1 , 5 ) includes sensitive regions, in which no and/or only insignificant interfering factors ( 17 , 23 ) are located and/or are to be expected, and for detection and/or tracking of the objects in motion ( 16 ) in the sensitive regions, a sensitive content analysis is performed, wherein a second region class (D 2 , 6 ) includes semi-sensitive regions ( 19 ), in which interfering factors ( 17 , 23 ) are located and/or are to be expected, and for detection and/or tracking of the objects in motion ( 16 ) in the semi-sensitive regions ( 19 ), a semi-sensitive content analysis is performed, which is limited and/or modified compared to the sensitive content analysis.
