Occluded Person Re-Identification via Relational Adaptive Feature Correction Learning
Occluded person re-identification (Re-ID) in images captured by multiple
cameras is challenging because the target person is occluded by pedestrians or
objects, especially in crowded scenes. In addition to the processes performed
during holistic person Re-ID, occluded person Re-ID involves the removal of
obstacles and the detection of partially visible body parts. Most existing
methods utilize the off-the-shelf pose or parsing networks as pseudo labels,
which are prone to error. To address these issues, we propose a novel Occlusion
Correction Network (OCNet) that corrects features through relational-weight
learning and obtains diverse and representative features without using external
networks. In addition, we present a simple concept of a center feature in order
to provide an intuitive solution to pedestrian occlusion scenarios.
Furthermore, we suggest the idea of Separation Loss (SL) for focusing on
different parts between global features and part features. We conduct extensive
experiments on five challenging benchmark datasets for occluded and holistic
Re-ID tasks to demonstrate that our method achieves superior performance to
state-of-the-art methods especially on occluded scene.Comment: ICASSP 202
