Just One Moment: Structural Vulnerability of Deep Action Recognition against One Frame Attack

no code implementations ICCV 2021 Jaehui Hwang, Jun-Hyuk Kim, Jun-Ho Choi, Jong-Seok Lee

In this paper, we study the structural vulnerability of deep learning-based action recognition models against the adversarial attack using the one frame attack that adds an inconspicuous perturbation to only a single frame of a given video clip.

MAMNet: Multi-path Adaptive Modulation Network for Image Super-Resolution

3 code implementations29 Nov 2018 Jun-Hyuk Kim, Jun-Ho Choi, Manri Cheon, Jong-Seok Lee

Specifically, we propose a multi-path adaptive modulation block (MAMB), which is a lightweight yet effective residual block that adaptively modulates residual feature responses by fully exploiting their information via three paths.

Deep Learning-based Image Super-Resolution Considering Quantitative and Perceptual Quality

1 code implementation13 Sep 2018 Jun-Ho Choi, Jun-Hyuk Kim, Manri Cheon, Jong-Seok Lee

Recently, it has been shown that in super-resolution, there exists a tradeoff relationship between the quantitative and perceptual quality of super-resolved images, which correspond to the similarity to the ground-truth images and the naturalness, respectively.
