In order to obtain a description of a TV-sequence by a natural language system the digitized sequences of TV-frames have to be evaluated automatically by a vision system and the resulting data have to be transferred in a suitable format to the natural language system. By analysis of displacement vector fields and the underlying feature trajectories, it is possible to give a description of moving objects, projected into the image plane, even when they come to a stop. The data from 130 TV-frames were used successfully by a natural language system. (IITB)
