High pass filters are typically used to highlight boundaries. An often used function is the Laplacian of Gaussian filter: log = fspecial ('log', [3 3],0.5); figure; freqz2 (log); Another one is the Laplacian filter:

The Wiener filter tailors itself to the local image variance. Where the variance is large, wiener2 performs little smoothing. Where the variance is small, wiener2 performs more smoothing. This approach often produces better results …
