A METHOD FOR INDIVIDUAL TRACKING OF MULTIPLE OBJECTS

摘要

The present invention relates to a tracking method, which is capable of individual tracking of multiple objects (such as people and their belongings) and an abandoned object detection method is proposed. Multiple objects are tracked using the proposed method. In addition to visible band, thermal images are also used and these two modalities are fused to track people and the objects they carry separately using their heat signatures. By using the information coming from different modalities, trajectories of the objects are found, ownership information for nonliving object is determined and abandoned objects are detected. Better tracking performance is also achieved compared to using single modality. We use adaptive background modeling and local intensity operation in association with mean-shift tracking for fully automatic tracking. Trackers are refreshed to resolve the possible problems which may occur due to changes in object's size, shape and to handle occlusion, split and to detect newly emerging objects as well as objects that leave the scene.
