Sequential Deep Trajectory Descriptor for Action Recognition With Three-Stream CNN
Sequential Deep Trajectory Descriptor for Action Recognition With Three-Stream CNN
Learning the spatial-temporal representation of motion information is crucial to human action recognition. Nevertheless, most of the existing features or descriptors cannot capture motion information effectively, especially for long-term motion. To address this problem, this paper proposes a long-term motion descriptor called sequential deep trajectory descriptor (sDTD). Specifically, we project …
