This particular "fix" is for chromatic aberration fringing -- see post on the previous page describing the particulars: http://originaltrilogy.com/forum/topic.cfm/THX-1138-preservations-Italian-Cut-available-see-1st-post/post/624565/#TopicPost624565. I wouldn't expect such a problem to be on a professional release.

However, if you are referring to effects of commercial publishers overusing their poorly implemented EE (Edge Enhancement), then, yes, there is a rudimentary Avisynth filter than can reduce that problem.

First, see post (also in this thread) for an explanation on the proper approach to "sharpen" an image, in Avisynth with the LimitedSharpen filter: http://originaltrilogy.com/forum/topic.cfm/THX-1138-preservations-Italian-Cut-available-see-1st-post/post/529702/#TopicPost529702.

For a possible reduction of EE fringing, see post (again, in this thread) for a demonstration of the DeHalo_alpha filter, also for Avisynth (I max'ed out the settings, for that demonstration, which created it's own problems): http://originaltrilogy.com/forum/topic.cfm/THX-1138-preservations-Italian-Cut-available-see-1st-post/post/552393/#TopicPost552393.

As always, filters are in constant development. Always research the Doom9 forums Avisynth sections for improved or new filtering.
