Human action recognition is still a challenging topic in the computer vision field that has attracted a large number of researchers. It has a significant importance in varieties of applications such as intelligent video surveillance, sports analysis, and human–computer interaction. Recent works attempt to exploit the progress in deep learning architecture to learn spatial and temporal features from action video. However, it remains unclear how to combine spatial and temporal information with convolutional neural network. In this paper, we propose a novel human action recognition method by fusing spatial and temporal features learned from a simple unsupervised convolutional neural network called principal component analysis network (PCANet) in combination with bag-of-features (BoF) and vector of locally aggregated descriptors (VLAD ) encoding schemes. Firstly, both spatial and temporal features are …
