Researchers have developed DA-Mamba, a novel framework for polarimetric synthetic aperture radar (PolSAR) image classification. This new architecture addresses limitations in existing Mamba-based methods by incorporating direction-adaptive scanning to better capture anisotropic scattering and weak boundaries crucial for PolSAR analysis. DA-Mamba also employs the Non-Subsampled Contourlet Transform (NSCT) to process data in both spatial and frequency domains, integrating global components with directional high-frequency features for enhanced discriminability. Experiments on three real-world PolSAR datasets demonstrate that DA-Mamba outperforms current state-of-the-art methods. AI
