Query: Collaborative Attention Network for Person Re-identification   Jointly utilizing global and local features to improve model accuracy is
becoming a popular approach for the person re-identification (ReID) problem,
because previous works using global features alone have very limited capacity
at extracting discriminative local patterns in the obtained feature
representation. Existing works that attempt to collect local patterns either
explicitly slice the global feature into several local pieces in a handcrafted
way, or apply the attention mechanism to implicitly infer the importance of
different local regions. In this paper, we show that by explicitly learning the
importance of small local parts and part combinations, we can further improve
the final feature representation for Re-ID. Specifically, we first separate the
global feature into multiple local slices at different scale with a proposed
multi-branch structure. Then we introduce the Collaborative Attention Network
(CAN) to automatically learn the combination of features from adjacent slices.
In this way, the combination keeps the intrinsic relation between adjacent
features across local regions and scales, without losing information by
partitioning the global features. Experiment results on several widely-used
public datasets including Market-1501, DukeMTMC-ReID and CUHK03 prove that the
proposed method outperforms many existing state-of-the-art methods.
