Diversity Regularized Spatiotemporal Attention for Video-based Person Re-identification 主旨:用空间注意力和时间注意力来解决遮挡和不对齐问题 自动地发现不同部位的注意力(即训练多个注意力模块) 不会受遮挡和不对齐影响(这里是因为时间上的注意力模块会自动择优(权值大的))...
Meanwhile, the spatial context and temporal information were not fully utilized and processed in some networks. In this paper, a novel three-stream network spatiotemporal attention enhanced features fusion network for action recognition is proposed. Firstly, features fusion stream which includes multi-...
Human action analytics has attracted a lot of attention for decades in computer vision. It is important to extract discriminative spatio-temporal features to model the spatial and temporal evolutions of different actions. In this paper, we propose a spatial and temporal attention model to explore th...

temporal deformable attention network (STDANet) for video delurring, which extracts the information of sharp pixels by considering the pixel-wise blur levels of the video frames. Specifically, STDANet is an encoder-decoder network combined with the motion estimator and spatio-temporal deformable ...
self-attention is widely applied in language inference tasks. Motivated by these observations, we propose a self-attention traffic matrix prediction (SATMP) model for long-term network TM prediction in IIoT scenarios. SATMP consists of three components: (a) a spatial–temporal encoding for obtaini...
