Improving Fairness in Deepfake Detection

1 code implementation29 Jun 2023 Yan Ju, Shu Hu, Shan Jia, George H. Chen, Siwei Lyu

Despite the development of effective deepfake detectors in recent years, recent studies have demonstrated that biases in the data used to train these detectors can lead to disparities in detection accuracy across different races and genders.

AutoSplice: A Text-prompt Manipulated Image Dataset for Media Forensics

1 code implementation14 Apr 2023 Shan Jia, Mingzhen Huang, Zhou Zhou, Yan Ju, Jialing Cai, Siwei Lyu

To achieve this, we propose a new approach that leverages the DALL-E2 language-image model to automatically generate and splice masked regions guided by a text prompt.

GLFF: Global and Local Feature Fusion for AI-synthesized Image Detection

1 code implementation16 Nov 2022 Yan Ju, Shan Jia, Jialing Cai, Haiying Guan, Siwei Lyu

To address this issue, we propose a Global and Local Feature Fusion (GLFF) framework to learn rich and discriminative representations by combining multi-scale global features from the whole image with refined local features from informative patches for AI synthesized image detection.

Fusing Global and Local Features for Generalized AI-Synthesized Image Detection

1 code implementation26 Mar 2022 Yan Ju, Shan Jia, Lipeng Ke, Hongfei Xue, Koki Nagano, Siwei Lyu

Specifically, we design a two-branch model to combine global spatial information from the whole image and local informative features from multiple patches selected by a novel patch selection module.

Modified Diversity of Class Probability Estimation Co-training for Hyperspectral Image Classification

no code implementations5 Sep 2018 Yan Ju, Lingling Li, Licheng Jiao, Zhongle Ren, Biao Hou, Shuyuan Yang

Due to the limited amount and imbalanced classes of labeled training data, the conventional supervised learning can not ensure the discrimination of the learned feature for hyperspectral image (HSI) classification.
