Dynamic Graph Learning With Content-Guided Spatial-Frequency Relation Reasoning for Deepfake Detection

no code implementations CVPR 2023 YuAn Wang, Kun Yu, Chen Chen, Xiyuan Hu, Silong Peng

To address this issue, we propose a Spatial-Frequency Dynamic Graph method to exploit the relation-aware features in spatial and frequency domains via dynamic graph learning.

Balanced Knowledge Distillation for Long-tailed Learning

1 code implementation21 Apr 2021 Shaoyu Zhang, Chen Chen, Xiyuan Hu, Silong Peng

Existing methods usually modify the classification loss to increase the learning focus on tail classes, which unexpectedly sacrifice the performance on head classes.

Progressive Bilateral-Context Driven Model for Post-Processing Person Re-Identification

1 code implementation7 Sep 2020 Min Cao, Chen Chen, Hao Dou, Xiyuan Hu, Silong Peng, Arjan Kuijper

Most existing person re-identification methods compute pairwise similarity by extracting robust visual features and learning the discriminative metric.

PCA-SRGAN: Incremental Orthogonal Projection Discrimination for Face Super-resolution

no code implementations1 May 2020 Hao Dou, Chen Chen, Xiyuan Hu, Zuxing Xuan, Zhisen Hu, Silong Peng

Generative Adversarial Networks (GAN) have been employed for face super resolution but they bring distorted facial details easily and still have weakness on recovering realistic texture.

Key Person Aided Re-identification in Partially Ordered Pedestrian Set

no code implementations25 May 2018 Chen Chen, Min Cao, Xiyuan Hu, Silong Peng

Ideally person re-identification seeks for perfect feature representation and metric model that re-identify all various pedestrians well in non-overlapping views at different locations with different camera configurations, which is very challenging.
