The proposed method utilizes the characteristics of the hierarchical structure of the video, and performed multi-level embedding feature extraction on the video frame sequence through the graph network, and obtained a video representation which reflects the event semantics hierarchically.
We use graph network to represent the relations between frames, shots, or events, that similar ones(nodes) have edge connected. The graph is gradually ag-.
