A Review of Hyperspectral Unmixing Considering Spectral Variability

Hyperspectral unmixing (HU) is a fundamental task in the analysis and interpretation of hyperspectral images. A large number of HU methods have been developed rapidly, and several review papers have summarized these developments. More recently, spectral variability (SV) has attracted increasing attention in HU, leading...

DSES-Diff: A Dynamic-Spectral and Efficient-Spatial Diffusion-Based Foundation Model for Scalable Hyperspectral and Multispectral Image Fusion

Hyperspectral image (HSI) and multispectral image (MSI) fusion is a critical technique for generating imagery with high spatial and spectral resolution. However, developing robust fusion models is fundamentally challenged by the severe scarcity of large-scale, precisely paired HSI-MSI datasets, which are prohibitively...

Native Sparse Attention for Optical Remote Sensing Spectral Images

Optical remote sensing (RS) spectral images contain rich cross-band response patterns. Recent RS foundation models (RSFMs) improve compatibility with variable-band inputs through unified or channelwise tokenization, but such input-interface compatibility does not ensure generalization to unseen sensors. Moreover, exist...
