Hierarchical Frequency-Guided Alignment Transformer for Compressed Video Quality Enhancement

Liuhan Peng, Shuai Li, Yanbo Gao, Mao Ye, Chong Lv

AAAI 2026technical

During the video encoding process, the original spatial domain signal is first transformed into the frequency domain, followed by quantization and compression. As a result, the quality degradation in compressed videos primarily stems from distortions in the frequency domain information. However, exi

MetaTeacher: Coordinating Multi-Model Domain Adaptation for Medical Image Classification

Zhenbin Wang, Mao Ye, Xiatian Zhu, Liuhan Peng, Liang Tian, Yingying Zhu

NeurIPS 2022accept

In medical image analysis, we often need to build an image recognition system for a target scenario with the access to small labeled data and abundant unlabeled data, as well as multiple related models pretrained on different source scenarios. This presents the combined challenges of multi-source-fr…
