A method for tracking moving objects crossing fields of view of multiple cameras is presented. The algorithm utilizes Artificial Neural Networks (ANNs). Each ANN is trained to recognize images of one moving object acquired by a single camera. Local image features calculated in the vicinity of automatically detected interest points are used as object image parameters. Next, ANNs are employed to identify the same objects captured by other cameras. Object tracking is supplemented by spatial and temporal constraints defining possible transitions between cameras' fields of view. Experiments carried out were focused on identification of the same vehicles in different cameras. The results achieved prove that the algorithm is sufficiently effective for multi-camera object tracking provided that the cameras' orientations with respect to moving objects and to the ground are similar.
