Query: Heterogeneous Relational Complement for Vehicle Re-identification   The crucial problem in vehicle re-identification is to find the same vehicle
identity when reviewing this object from cross-view cameras, which sets a
higher demand for learning viewpoint-invariant representations. In this paper,
we propose to solve this problem from two aspects: constructing robust feature
representations and proposing camera-sensitive evaluations. We first propose a
novel Heterogeneous Relational Complement Network (HRCN) by incorporating
region-specific features and cross-level features as complements for the
original high-level output. Considering the distributional differences and
semantic misalignment, we propose graph-based relation modules to embed these
heterogeneous features into one unified high-dimensional space. On the other
hand, considering the deficiencies of cross-camera evaluations in existing
measures (i.e., CMC and AP), we then propose a Cross-camera Generalization
Measure (CGM) to improve the evaluations by introducing position-sensitivity
and cross-camera generalization penalties. We further construct a new benchmark
of existing models with our proposed CGM and experimental results reveal that
our proposed HRCN model achieves new state-of-the-art in VeRi-776, VehicleID,
and VERI-Wild.
