A Unified Multi-Task Learning Framework of Real-Time Drone Supervision for Crowd Counting

no code implementations8 Feb 2022 Siqi Gu, Zhichao Lian

In this paper, a novel Unified Multi-Task Learning Framework of Real-Time Drone Supervision for Crowd Counting (MFCC) is proposed, which utilizes an image fusion network architecture to fuse images from the visible and thermal infrared image, and a crowd counting network architecture to estimate the density map.

Real-centric Consistency Learning for Deepfake Detection

no code implementations15 May 2022 Ruiqi Zha, Zhichao Lian, Qianmu Li, Siqi Gu

Essentially, the target of deepfake detection problem is to represent natural faces and fake faces at the representation space discriminatively, and it reminds us whether we could optimize the feature extraction procedure at the representation space through constraining intra-class consistence and inter-class inconsistence to bring the intra-class representations close and push the inter-class representations apart?

Boost Adversarial Transferability by Uniform Scale and Mix Mask Method

no code implementations18 Nov 2023 Tao Wang, Zijian Ying, Qianmu Li, Zhichao Lian

To address these challenges, we propose a framework called Uniform Scale and Mix Mask Method (US-MM) for adversarial example generation.

Adversarial Purification of Information Masking
