文摘

Novel spectral-spatial adaptive and WBF-based multispectral AD model is proposed. A new sigmoid function is used to balance the two terms in the proposed PDE. The fidelity term in the PDE is adaptive by employing the smoothed result. Our model respects spatial intensity and spectral signature differences in images. Our model can better control the diffusion behavior than other MAD models.
