Weighted essentially non-oscillatory schemes are described in detail for a total variation-based image restoration problem with Gaussian kernel at different boundary conditions. Numerical results with three methods （weighted essentially nonoscillatory schemes, wiener algorithm and a combination of them） are compared. Experimental results demonstrate effectiveness of the combination of weighted essentially non-oscillatory schemes and wiener algorithm.
