Slow feature subspace: A video representation based on slow feature analysis for action recognition
Machine Learning with Applications, 2023 This paper proposes a new video representation for subspace-based action recognition. Traditional subspace-based methods represent a video as a subspace by applying principal component analysis (PCA) to its frames. However, this subspace might lead to an
