HyperVision introduces the first ground‑based hyperspectral pre‑trained backbone, addressing challenges of varying spectral configurations, limited annotations, and dataset diversity. It employs a channel‑adaptive dynamic embedding to unify heterogeneous inputs, a multi‑source pseudo‑labeling strategy combining SAM2 spatial cues with HyperFree spectral details, and cross‑modal knowledge distillation from a pre‑trained RGB vision model. Trained on 15k images from 26 datasets, HyperVision achieves significant improvements—up to 16.3% relative gain in hyperspectral semantic segmentation, 2.1% in object tracking AUC, and 35.5% reduction in salient object detection MAE—while requiring only head‑only adaptation.

Token Clustering and Semantic Sequence Mamba (STMamba) is a new approach for hyperspectral image classification that organizes sparse tokens into semantically coherent sequences. It uses a hierarchical encoder-decoder with a Token Clustering Module (TCM) to select semantic tokens and a Cross-scale Neighborhood Attention (CNA) Upsampler to restore dense features. At the micro level, density-aware clustering and a quadtree-based dynamic selection keep sparse, spatially distributed tokens, while Spatial and Spectral Semantic-wise Sequencing Mamba (SWSM) modules capture long-range spatial and spectral dependencies within homogeneous semantic token sequences. Experiments on three large-scale benchmark datasets show that STMamba outperforms state‑of‑the‑art methods in both quantitative and qualitative metrics.
