Self-Supervised One-Step Diffusion Refinement for Snapshot Compressive Imaging

AAAI 2026technical

Snapshot compressive imaging (SCI) captures multispectral images (MSIs) using a single coded two-dimensional (2-D) measurement, but reconstructing high-fidelity MSIs from these compressed inputs remains a fundamentally ill-posed challenge. Recent diffusion-based methods improve quality but are limit

World-Model Inspired Emotion-aware Token Refinement for Training-Free Multimodal Emotion Recognition

ICML 2026spotlight

Multimodal Large Language Models (MLLMs) show promise for Multimodal Emotion Recognition (MER) but often remain unreliable because sparse emotional cues could be easily overwhelmed and affected by redundant context. While fine-tuning is effective, it is usually costly when using large models. Traini…

Heterogeneous Data-based Cross-domain Few-shot Classification Method of Hyperspectral Image

ICASSP 2025accepted

Few-shot learning (FSL) has been employed in hyperspectral image (HSI) classification, achieving excellent performance with limited training data. However, existing HSI few-shot classification methods often encounter the problem of insufficient domain-transferable knowledge learning that is either f…

Learning without Exact Guidance: Updating Large-scale High-resolution Land Cover Maps from Low-resolution Historical Labels

CVPR 2024highlight

Large-scale high-resolution (HR) land-cover mapping is a vital task to survey the Earth's surface and resolve many challenges facing humanity. However it is still a non-trivial task hindered by complex ground details various landforms and the scarcity of accurate training labels over a wide-span geo…

Spectrum-Aware and Transferable Architecture Search for Hyperspectral Image Restoration

ECCV 2022poster

"Convolutional neural networks have been widely developed for hyperspectral image (HSI) restoration. However, making full use of the spatial-spectral information of HSIs still remains a challenge. In this work, we disentangle the 3D convolution into lightweight 2D spatial and spectral convolutions,…
