Breaking Temporal Consistency: Generating Video Universal Adversarial Perturbations Using Image Models

no code implementations ICCV 2023 Hee-Seon Kim, Minji Son, Minbeom Kim, Myung-Joon Kwon, Changick Kim

To address this challenge, we introduce the Breaking Temporal Consistency (BTC) method, which is the first attempt to incorporate temporal information into video attacks using image models.

Introducing Competition to Boost the Transferability of Targeted Adversarial Examples through Clean Feature Mixup

1 code implementation CVPR 2023 Junyoung Byun, Myung-Joon Kwon, Seungju Cho, Yoonji Kim, Changick Kim

Deep neural networks are widely known to be susceptible to adversarial examples, which can cause incorrect predictions through subtle input modifications.

Improving the Transferability of Targeted Adversarial Examples through Object-Based Diverse Input

2 code implementations CVPR 2022 Junyoung Byun, Seungju Cho, Myung-Joon Kwon, Hee-Seon Kim, Changick Kim

To tackle this limitation, we propose the object-based diverse input (ODI) method that draws an adversarial image on a 3D object and induces the rendered image to be classified as the target class.

DHNet: Double MPEG-4 Compression Detection via Multiple DCT Histograms

no code implementations19 Jul 2021 Seung-Hun Nam, Wonhyuk Ahn, Myung-Joon Kwon, Jihyeon Kang, In-Jae Yu

In this article, we aim to detect the double compression of MPEG-4, a universal video codec that is built into surveillance systems and shooting devices.

Frame-rate Up-conversion Detection Based on Convolutional Neural Network for Learning Spatiotemporal Features

no code implementations25 Mar 2021 Minseok Yoon, Seung-Hun Nam, In-Jae Yu, Wonhyuk Ahn, Myung-Joon Kwon, Heung-Kyu Lee

The proposed network uses a stack of consecutive frames as the input and effectively learns interpolation artifacts using network blocks to learn spatiotemporal features.
