Abstract

This paper introduces RSTNet, a neural network model based on spatio-temporal attention (STA), designed to improve the accuracy of human action recognition. The model uses heatmaps as input, employs 3D-ResNet as its backbone network, and incorporates STA modules and squeeze-and-excitation (SE) modules. Experiments on the UCF101 dataset demonstrate that RSTNet outperforms other classic methods in key metrics such as Top1 accuracy, Top5 accuracy and average accuracy. Ablation studies further validate the contribution of each module to the model's performance, proving the effectiveness of this approach in capturing spatio-temporal features and enhancing action recognition precision.

RSTNet：一个用于人类动作识别的时空注意框架

本文介绍了一种基于时空注意（STA）的神经网络模型RSTNet，旨在提高人类动作识别的准确性。该模型以热图为输入，以3D-ResNet为骨干网络，结合STA模块和挤压激励（SE）模块。在UCF101数据集上的实验表明，RSTNet在Top1准确率、Top5准确率和平均准确率等关键指标上优于其他经典方法。消融研究进一步验证了每个模块对模型性能的贡献，证明了该方法在捕获时空特征和提高动作识别精度方面的有效性。
