ProtoHPE: Prototype-guided High-frequency Patch Enhancement for Visible-Infrared Person Re-identification

no code implementations11 Oct 2023 Guiwei Zhang, Yongfei Zhang, Zichang Tan

In contrast, we find that some cross-modal correlated high-frequency components contain discriminative visual patterns and are less affected by variations such as wavelength, pose, and background clutter than holistic images.

PHA: Patch-Wise High-Frequency Augmentation for Transformer-Based Person Re-Identification

no code implementations CVPR 2023 Guiwei Zhang, Yongfei Zhang, Tianyu Zhang, Bo Li, ShiLiang Pu

Although recent studies empirically show that injecting Convolutional Neural Networks (CNNs) into Vision Transformers (ViTs) can improve the performance of person re-identification, the rationale behind it remains elusive.

CAKE: A Scalable Commonsense-Aware Framework For Multi-View Knowledge Graph Completion

1 code implementation ACL 2022 Guanglin Niu, Bo Li, Yongfei Zhang, ShiLiang Pu

The previous knowledge graph embedding (KGE) techniques suffer from invalid negative sampling and the uncertainty of fact-view link prediction, limiting KGC's performance.

Background Segmentation for Vehicle Re-Identification

no code implementations15 Oct 2019 Mingjie Wu, Yongfei Zhang, Tianyu Zhang, Wen-qi Zhang

Vehicle re-identification (Re-ID) is very important in intelligent transportation and video surveillance. Prior works focus on extracting discriminative features from visual appearance of vehicles or using visual-spatio-temporal information. However, background interference in vehicle re-identification have not been explored. In the actual large-scale spatio-temporal scenes, the same vehicle usually appears in different backgrounds while different vehicles might appear in the same background, which will seriously affect the re-identification performance.

Single Camera Training for Person Re-identification

1 code implementation24 Sep 2019 Tianyu Zhang, Lingxi Xie, Longhui Wei, Yongfei Zhang, Bo Li, Qi Tian

Differently, this paper investigates ReID in an unexplored single-camera-training (SCT) setting, where each person in the training set appears in only one camera.
