FWIW, I wrote a version of the comparison in Go that does the entire comparison in-memory, without shelling out to any program. I did this because it parallelized much better (ie. is faster), but it also means you can easily test alternative algorithms.
See here: https://github.com/hanwen/lilypond-ci/blob/master/cmd/compare/main.go Given the example you cite, maybe calculating optical flow would let you detect and filter general motion of objects between two frames, but from a quick look, it seems involved.
