Rethinking Class-Incremental Learning from a Dynamic Imbalanced Learning Perspective
Leyuan Wang, Liuyu Xiang, Yunlong Wang +2
Deep neural networks suffer from catastrophic forgetting when continually learning new concepts. In this paper, we analyze this problem from a data imbalance point of view. We argu…
CLIP model is an Efficient Online Lifelong Learner
Leyuan Wang, Liuyu Xiang, Yujie Wei +2
Online Lifelong Learning (OLL) addresses the challenge of learning from continuous and non-stationary data streams. Existing online lifelong learning methods based on image classif…
An End-to-End Autofocus Camera for Iris on the Move
Leyuan Wang, Kunbo Zhang, Yunlong Wang +1
For distant iris recognition, a long focal length lens is generally used to ensure the resolution ofiris images, which reduces the depth of field and leads to potential defocus blu…
Recognition Oriented Iris Image Quality Assessment in the Feature Space
Leyuan Wang, Kunbo Zhang, Min Ren +2
A large portion of iris images captured in real world scenarios are poor quality due to the uncontrolled environment and the non-cooperative subject. To ensure that the recognition…
Face Anti-Spoofing by Learning Polarization Cues in a Real-World Scenario
Yu Tian, Kunbo Zhang, Leyuan Wang +1
Face anti-spoofing is the key to preventing security breaches in biometric recognition applications. Existing software-based and hardware-based face liveness detection methods are…
