Instruct2Attack: Language-Guided Semantic Adversarial Attacks

Jiang Liu, Chen Wei, Yuxiang Guo +5

We propose Instruct2Attack (I2A), a language-guided semantic attack that generates semantically meaningful perturbations according to free-form language instructions. We make use o…

Interpolated Joint Space Adversarial Training for Robust and Generalizable Defenses

Chun Pong Lau, Jiang Liu, Hossein Souri +3

Adversarial training (AT) is considered to be one of the most reliable defenses against adversarial attacks. However, models trained with AT sacrifice standard accuracy and do not…

Mutual Adversarial Training: Learning together is better than going alone

Jiang Liu, Chun Pong Lau, Hossein Souri +2

Recent studies have shown that robustness to adversarial attacks can be transferred across networks. In other words, we can make a weak model more robust with the help of a strong…

Subsampled Turbulence Removal Network

Wai Ho Chak, Chun Pong Lau, Lok Ming Lui

We present a deep-learning approach to restore a sequence of turbulence-distorted video frames from turbulent deformations and space-time varying blurs. Instead of requiring a mass…

Variational models for joint subsampling and reconstruction of turbulence-degraded images

Chun Pong Lau, Yu Hin Lai, Lok Ming Lui

Turbulence-degraded image frames are distorted by both turbulent deformations and space-time-varying blurs. To suppress these effects, we propose a multi-frame reconstruction schem…

Image retargeting via Beltrami representation

Chun Pong Lau, Chun Pang Yung, Lok Ming Lui

Image retargeting aims to resize an image to one with a prescribed aspect ratio. Simple scaling inevitably introduces unnatural geometric distortions on the important content of th…
