Instruct2Attack: Language-Guided Semantic Adversarial Attacks

no code implementations27 Nov 2023 Jiang Liu, Chen Wei, Yuxiang Guo, Heng Yu, Alan Yuille, Soheil Feizi, Chun Pong Lau, Rama Chellappa

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

GaitContour: Efficient Gait Recognition based on a Contour-Pose Representation

no code implementations27 Nov 2023 Yuxiang Guo, Anshul Shah, Jiang Liu, Ayush Gupta, Rama Chellappa, Cheng Peng

Gait recognition holds the promise to robustly identify subjects based on walking patterns instead of appearance information.

Multi-Modal Human Authentication Using Silhouettes, Gait and RGB

no code implementations8 Oct 2022 Yuxiang Guo, Cheng Peng, Chun Pong Lau, Rama Chellappa

In this work, we propose Dual-Modal Ensemble (DME), which combines both RGB and silhouette data to achieve more robust performances for indoor and outdoor whole-body based recognition.
