GloTok: Global Perspective Tokenizer for Image Reconstruction and Generation

AAAI 2026technical

Existing state-of-the-art image tokenization methods leverage diverse semantic features from pre-trained vision models for additional supervision, to expand the distribution of latent representations and thereby improve the quality of image reconstruction and generation. These methods employ a local

Data Synthesis with Diverse Styles for Face Recognition via 3DMM-Guided Diffusion

CVPR 2025poster

Identity-preserving face synthesis aims to generate synthetic face images of virtual subjects that can substitute real-world data for training face recognition models. While prior arts strive to create images with consistent identities and diverse styles, they face a trade-off between them. Identify…

EyeSeg: An Uncertainty-Aware Eye Segmentation Framework for AR/VR

IJCAI 2025

Human-machine interaction through augmented reality (AR) and virtual reality (VR) is increasingly prevalent, requiring accurate and efficient gaze estimation which hinges on the accuracy of eye segmentation to enable smooth user experiences. We introduce EyeSeg, a novel eye segmentation framework de

One-for-More: Continual Diffusion Model for Anomaly Detection

CVPR 2025poster

With the rise of generative models, there is a growing interest in unifying all tasks within a generative framework. Anomaly detection methods also fall into this scope and utilize diffusion models to generate or reconstruct normal samples when given arbitrary anomaly images. However, our study foun…

PVTree: Realistic and Controllable Palm Vein Generation for Recognition Tasks

AAAI 2025technical

Palm vein recognition is an emerging biometric technology that offers enhanced security and privacy. However, acquiring sufficient palm vein data for training deep learning-based recognition models is challenging due to the high costs of data collection and privacy protection constraints. This has l…

SlerpFace: Face Template Protection via Spherical Linear Interpolation

AAAI 2025technical

Contemporary face recognition systems use feature templates extracted from face images to identify persons. To enhance privacy, face template protection techniques are widely employed to conceal sensitive identity and appearance information stored in the template. This paper identifies an emerging p…

Boundary-aware Decoupled Flow Networks for Realistic Extreme Rescaling

IJCAI 2024poster

Recently developed generative methods, including invertible rescaling network (IRN) based and generative adversarial network (GAN) based methods, have demonstrated exceptional performance in image rescaling. However, IRN-based methods tend to produce over-smoothed results, while GAN-based methods ea…

DFD: Distilling the Feature Disparity Differently for Detectors

ICML 2024poster

Knowledge distillation is a widely adopted model compression technique that has been successfully applied to object detection. In feature distillation, it is common practice for the student model to imitate the feature responses of the teacher model, with the underlying objective of improving its ow…
