| 英文摘要 | Group motion direction, which is composed of instant consistent motions, is an interesting property in group dynamics. Understanding the instant group motiondirection is a key component of crowd analysis and has a wide range of applications, especially for improving group detection in crowd. In this study, independent from group detection methods, we propose an instant group motion refining framework based on group motion direction. We show that instantgroup motion direction can be systematically quantified by intra-group motion consistency. This is achieved by proposing two instant group motionrepresentations in terms of velocity consistency and angle consistency. These group motion representations provide a new way to derive the instant groupmotion direction, which plays an important role in improving the performance of state-of-the-art group detection methods. Besides, to improve traditional groupdetection methods, a novel group detection method is proposed as well. Extensive experiments on a variety of public scene video clips demonstrate that both group motion consistency representations are not only useful but also necessary for instant group coherent motion filtering.
