This automated method looks interesting, I love the colours.

Could it be used for fixing faded 8mm film, e.g. something like this ?

In principle yes, but it depends somewhat on, whether the film meets the underlying assumptions of the color correction model. One of those assumptions is that over the run of a reel/film the fading is similar across frames, and another is that over the run of a reel/film, each of the colors magenta, yellow, and cyan, are equally probable to occur. Consequently, the model needs enough shifted frames, to predict an accurate correction.
