Tensor Representations for Action Recognition
IEEE Transactions on Pattern Analysis and Machine Intelligence(2022)
摘要
Human actions in video sequences are characterized by the complex interplay between spatial features and their temporal dynamics. In this paper, we propose novel tensor representations for compactly capturing such higher-order relationships between visual features for the task of action recognition. We propose two tensor-based feature representations, viz. (i) sequence compatibility kernel...
