| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper proposes a Tensor Decomposition Based method that can recognize an unknown person’s action from a video sequence, where the unknown person is not included in the database (tensor) used for the recognition. The tensor consists of persons, actions and time-series image features. For the observed unknown person’s action, one of the actions stored in the tensor is assumed. Using the motion signature obtained from the assumption, the unknown person’s actions are synthesized. The actions of one of the persons in the tensor are replaced by the synthesized actions. Then, the core tensor for the replaced tensor is computed. This process is repeated for the actions and persons. For each iteration, the difference between the replaced and original core tensors is computed. The assumption that gives the minimal difference is the action recognition result. Three image features are tested for recognition experiments. Experiments using 15 persons’ seven kinds of action show the effectiveness of the recognition method and clarify the useful image features. | |
