Multi-Scale Spectral Attention Module-based Hyperspectral Segmentation in Autonomous Driving Scenarios

Read the original on arXiv AI →

The paper investigates a Multi-Scale Spectral Attention Module (MSAM) for hyperspectral image segmentation in autonomous driving. MSAM uses three parallel 1D convolutions with different kernel sizes (1–11) and adaptive feature aggregation, integrated into UNet’s skip connections. Experiments on urban driving datasets show that MSAM improves mIoU by 2.32% and mF1 by 2.88% over baseline UNet-SC while keeping GPU performance competitive, with optimal kernel combinations varying by dataset.

HyperVision: A Channel-Adaptive Ground-Based Hyperspectral Vision Pre-trained Backbone

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 for Hyperspectral Image Classification

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.
