Motion Transfer-Driven Intra-Class Data Augmentation for Finger Vein Recognition

ICASSP 2024accepted

Finger vein recognition (FVR) has emerged as a secure biometric technique because of the confidentiality of vascular bio-information. Recently, deep learning-based FVR has gained increased popularity and achieved promising performance. However, the limited size of public vein datasets has caused ove…

Contrastive Spatio-Temporal Pretext Learning for Self-Supervised Video Representation

AAAI 2022technical

Spatio-temporal representation learning is critical for video self-supervised representation. Recent approaches mainly use contrastive learning and pretext tasks. However, these approaches learn representation by discriminating sampled instances via feature similarity in the latent space while ignor…
