MambaAD: Exploring State Space Models for Multi-class Unsupervised Anomaly Detection

NeurIPS 2024poster

Recent advancements in anomaly detection have seen the efficacy of CNN- and transformer-based approaches. However, CNNs struggle with long-range dependencies, while transformers are burdened by quadratic computational complexity. Mamba-based models, with their superior long-range modeling and linear…

MixTeacher: Mining Promising Labels With Mixed Scale Teacher for Semi-Supervised Object Detection

CVPR 2023poster

Scale variation across object instances is one of the key challenges in object detection. Although modern detection models have achieved remarkable progress in dealing with the scale variation, it still brings trouble in the semi-supervised case. Most existing semi-supervised object detection method…

Designing One Unified Framework for High-Fidelity Face Reenactment and Swapping

ECCV 2022poster

"Face reenactment and swapping share a similar identity and attribute manipulating pattern, but most methods treat them separately, which is redundant and practical-unfriendly. In this paper, we propose an effective end-to-end unified framework to achieve both tasks. Unlike existing methods that dir…
