[1909.02240] Adaptive Graph Representation Learning for Video Person Re-identification

Recent years have witnessed a great development of deep learning based video person re-identification (Re-ID). A key factor for video person Re-ID is how to effectively construct discriminative video feature representations for the robustness to many complicated situations like occlusions. Recent part-based approaches employ spatial and temporal attention to extract the representative local features. While the correlations between the parts are ignored in the previous methods, to leverage the relations of different parts, we propose an innovative adaptive graph representation learning scheme for video person Re-ID, which enables the contextual interactions between the relevant regional features. Specifically, we exploit pose alignment connection and feature affinity connection to construct an adaptive structure-aware adjacency graph, which models the intrinsic relations between graph nodes. We perform feature propagation on the adjacency graph to refine the original regional features i

@rschu Re-Identifying persons in videos even better with this new #AI Graph #DeepLearning approach. 🧠 They also leverage the pose and mapped into a graph to re-identify persons even in tricky, occluded frames. 👏 Of course this has #AIEthics implications. 🤔 t.co/QA60u13aCH t.co/cK4oY5oPwg
