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.
