TBSA: Tri-Domain Balanced Spectral–Spatial Attention with Deformable Frequency Filtering for Hyperspectral Image Classification
Tri-Domain Balanced Spectral–Spatial Attention (TBSA), a compact frequency-aware framework for HSIC, projects intermediate features into one-dimensional spectral, two-dimensional spatial, and three-dimensional spectral–spatial discrete cosine transform (DCT) domains, and it introduces a deformable frequency filter to a...
