| Summary: | Workflow detection is a challenge issue in the process of Industry 4.0, which plays a crucial role in intelligent production.
However, it faces the problem of inaccurate phase classification and unclear boundary positioning, which are not well resolved
in previous works. To solve them, this paper develops a temporal-aware workflow detection framework (TransGAN) which takes
advantage of the complementarity between Transformer and graph attention network to improve phase discriminability.
Specifically, temporal self-attention is firstly designed to learn the relationship between different positions of
feature sequence. Then, multi-scale Transformer is introduced to encode pyramid features, which fuses multiple context
cues for discriminative feature representation. At last, contextual and surrounding relations are learned in graph
attention network for refined phase classification and boundary localization. Comprehensive experiments are performed
to verify the effectiveness of our method. Compared to the advanced AFSD, the accuracy is improved by 2.3 % and 2.1 % when
tIoU=0.5 on POTFD and THUMOS-14 dataset, respectively. Empirical study of running speed indicates that the proposed TransGAN
can be deployed to real-world industrial environment for workflow detection. |
