Closed-Form Nonlocal Shrinkage for Multiplicative Image Denoising and SAR Despeckling

Multiplicative noise poses a challenge in coherent and signal-dependent imaging owing to its intensity-dependent variance and frequently non-Gaussian distribution. We propose a deterministic nonlocal estimator that combines a logarithmic Yeo--Johnson transformation, patch grouping, an adaptive singular basis, and spars...

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...
