FFTNet2D: A Novel Frequency Domain Framework for Hyperspectral Image Classification

Hyperspectral image (HSI) classification remains challenging because accurate recognition requires both global contextual modeling and computationally efficient processing of high-dimensional spectral–spatial data. Transformer-based methods can capture long-range interactions, but their quadratic token-mixing cost limi...

TBSA: Tri-Domain Balanced Spectral–Spatial Attention with Deformable Frequency Filtering for Hyperspectral Image Classification

Hyperspectral image classification (HSIC) requires a classifier to distinguish land-cover categories from densely sampled spectral signatures while preserving the spatial arrangement of local materials. Although convolutional networks, Transformer architectures, and recent state-space models have greatly improved spect...

SSH-Net: Symplectic-Inspired Discrete Dynamic Evolution for Hyperspectral Image Classification

Hyperspectral image classification (HSIC) relies on effective modeling of coupled spectral–spatial interactions. While recent CNN-, Transformer-, and Mamba-based methods have improved feature extraction, most of them organize token interaction through layerwise aggregation and repeated stacking, leaving cross-layer pro...
