PF-Trans: Physics-Embedded Frequency-Aware Transformer for Spectral Reconstruction
Researchers have developed PF-Trans, a novel Transformer model designed for spectral reconstruction in remote sensing. This model integrates physics-based principles and frequency-domain analysis to effectively address spectral aliasing, a common issue in snapshot broadband filter array imaging. PF-Trans achieves state-of-the-art performance, demonstrated by a Peak Signal-to-Noise Ratio of up to 48.50 dB on a specific dataset. AI
