- Abstract:

To solve the problem of double interaction behavior recognition, in this paper we propose a novel interaction behavior-recognition method based on hierarchical structure. First, the interactive behavior of both areas of body contact is determined as the cut-off point. The interaction process is then divided into three stages-the start, execution, and end stages. We extract the left and right human body regions in the start and end stages, respectively. Both human body regions are extracted as a whole in the execute stage. Next, we utilize a histogram of oriented gradients(HOG) descriptor to describe information on the regions of interest of each stage. Thereafter, we use the nearest neighbor classifier to obtain the recognition probability of each object in each stage. Finally, we obtain the recognition result from the weighted fusion of this recognition probability. The experimental results, using the UT-interaction dataset, demonstrate that the proposed approach is easy to implement and has good recognition effect.
