Slow feature analysis deep learning
Webb23 juni 2014 · This paper proposes 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. 19 WebbSlow Feature Analysis High level semantic concepts usually evolve slower than the low level image appear-ance in videos. The deep features are thus expected to vary …
