Exploiting Style Latent Flows for Generalizing Deepfake Detection Video Detection

no code implementations11 Mar 2024 Jongwook Choi, TaeHoon Kim, Yonghyun Jeong, Seungryul Baek, Jongwon Choi

This paper presents a new approach for the detection of fake videos, based on the analysis of style latent vectors and their abnormal behavior in temporal changes in the generated videos.

One-Shot Structure-Aware Stylized Image Synthesis

1 code implementation27 Feb 2024 Hansam Cho, Jonghyun Lee, Seunggyu Chang, Yonghyun Jeong

While GAN-based models have been successful in image stylization tasks, they often struggle with structure preservation while stylizing a wide range of input images.

Noise Map Guidance: Inversion with Spatial Context for Real Image Editing

1 code implementation7 Feb 2024 Hansam Cho, Jonghyun Lee, Seoung Bum Kim, Tae-Hyun Oh, Yonghyun Jeong

Text-guided diffusion models have become a popular tool in image synthesis, known for producing high-quality and diverse images.

Compose and Conquer: Diffusion-Based 3D Depth Aware Composable Image Synthesis

1 code implementation17 Jan 2024 Jonghyun Lee, Hansam Cho, Youngjoon Yoo, Seoung Bum Kim, Yonghyun Jeong

Addressing the limitations of text as a source of accurate layout representation in text-conditional diffusion models, many works incorporate additional signals to condition certain attributes within a generated image.

Scaling of Class-wise Training Losses for Post-hoc Calibration

1 code implementation19 Jun 2023 Seungjin Jung, Seungmo Seo, Yonghyun Jeong, Jongwon Choi

The class-wise training losses often diverge as a result of the various levels of intra-class and inter-class appearance variation, and we find that the diverging class-wise training losses cause the uncalibrated prediction with its reliability.

FrePGAN: Robust Deepfake Detection Using Frequency-level Perturbations

no code implementations7 Feb 2022 Yonghyun Jeong, Doyeon Kim, Youngmin Ro, Jongwon Choi

For experiments, we design new test scenarios varying from the training settings in GAN models, color manipulations, and object categories.

Self-supervised GAN Detector

no code implementations12 Nov 2021 Yonghyun Jeong, Doyeon Kim, Pyounggeon Kim, Youngmin Ro, Jongwon Choi

Although the recent advancement in generative models brings diverse advantages to society, it can also be abused with malicious purposes, such as fraud, defamation, and fake news.

MToFNet: Object Anti-Spoofing with Mobile Time-of-Flight Data

no code implementations6 Oct 2021 Yonghyun Jeong, Doyeon Kim, Jaehyeon Lee, Minki Hong, Solbi Hwang, Jongwon Choi

When images are recaptured on display screens, various patterns differing by the screens as known as the moir\'e patterns can be also captured in spoof images.

Toward Spatially Unbiased Generative Models

2 code implementations ICCV 2021 Jooyoung Choi, Jungbeom Lee, Yonghyun Jeong, Sungroh Yoon

From our observations, the generator's implicit positional encoding is translation-variant, making the generator spatially biased.
