StegaVAR: Privacy-Preserving Video Action Recognition via Steganographic Domain Analysis

AAAI 2026technical

Despite the rapid progress of deep learning in video action recognition (VAR) in recent years, privacy leakage in videos remains a critical concern. Current state-of-the-art privacy-preserving methods often rely on anonymization. These methods suffer from (1) low concealment, where producing visuall

EvaSR: Rethinking Efficient Visual Attention Design for Image Super-Resolution

ICASSP 2025accepted

Due to the advantages of long-range modeling via the self-attention mechanism, Transformer has taken various vision tasks by storm, including image super-resolution (SR). In this study, we reveal that the convolutional neural network (CNN) with proper visual attention is a more simple and effective…

GCAT: Gated Convolutional Attention Transformer for Efficient Image Super-Resolution

ICASSP 2025accepted

Recently, Transformer-based methods have achieved impressive performance in many computer vision tasks (e.g., image super-resolution (SR)) due to the advantages of long-range modeling. However, the computational cost requirement renders these methods unsuitable on resource-constrain devices, especia…

Imagination-Limited Q-Learning for Offline Reinforcement Learning

IJCAI 2025

Offline reinforcement learning seeks to derive improved policies entirely from historical data but often struggles with over-optimistic value estimates for out-of-distribution (OOD) actions. This issue is typically mitigated via policy constraint or conservative value regularization methods. However

DMKD: Improving Feature-Based Knowledge Distillation for Object Detection Via Dual Masking Augmentation

ICASSP 2024accepted

Recent mainstream masked distillation methods function by reconstructing selectively masked areas of a student network from the feature map of its teacher counterpart. In these methods, the masked regions need to be properly selected, such that reconstructed features encode sufficient discrimination…
