Try medfilt2, imfilter, imnlmfilt.

For the images corrupted by lines or stripes, it looks like they were just brightened or darkened by some factor. You can determine that factor by using sum() to sum the image horizontally and vertically and look at the ratio between means of bright strips and the means of the two darker strips on each site.
