【CVPR2023】Temporal Attention Unit: Towards Efficient Spatiotemporal Predictive Learning 高峰OUC 中国海洋大学,计算机学院教师8 人赞同了该文章 这个论文研究时空预测学习(spatiotemporal predictive learning),这是一种通过学习历史视频帧来生成未来视频帧的方法。 作者认为,当前方法基本上都使用相似的框架,即编...
Temporal attentionManifold spaceRecently, skeleton-based action recognition has become increasingly prevalent in computer vision due to its wide range of applications, and many approaches have been proposed to address this task. Among these methods, manifold space is widely used to deal with the ...
注意这里是有多个mask的(每个部件一个),然后通过加到损失函数里的损失项,使得他们聚焦于不同的位置。 softmax的实现 mask乘上如图特征图:(学名叫spatial gated feature) 注意得到的map还要经过一次增强。 具体细节不清楚 Attention model 的多样性正则
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-level features fusion blocks, is designed to train the two streams jointly and complement the two-stream network...
We propose a spatiotemporal attention based deep neural networks for dimensional emotion recognition in facial videos. To learn the spatiotemporal attention that selectively focuses on emotional sailient parts within facial videos, we formulate the spatiotemporal encoder-decoder network using Convolutional ...
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...
