Weighted laplacian differences based multispectral anisotropic diffusion
V. B. Surya Prasath · 2011
We study a multichannel version of nonlinear diffusion PDE which is used to restore noisy multispectral images. Weighted coupling of interchannel edges is done by utilizing fast total variation for each channel. Anisotropic intrachannel smoothing is included to denoise and preserve edges. Numerical results on noisy multispectral images show the advantage of the proposed hybrid approach.
