Nice finding.:)
Note on the last one: It's really not very hard to implement something quite similar with a script.
The following should give the idea (example is actually not-working, it's just to show a possible general flow)
dark = last
bright = dark .levels(...) # or Tweak(), ColorYUV(), HDRAGC() ... or whatever suits you
diff = mt_makediff( dark, bright, U=3,V=3 )
bvec1 = dark .MVAnalyse( isb=true, idx=1 )
fvec1 = dark .MVAnalyse( isb=false,idx=1 )
diff_temp = diff1.MVDegrain1( bvec,fvec, idx=2 ) # or use MVDegrain2/3 with more vectors
diff_spat = diff1. MinBlur(2) # or use tbilateral; MinBlur is the fast+lazy shortcut
err_bw = dark.MVMask( bvec1, kind=1, ml=50 ) # tweak ml, perhaps also gamma
err_fw = dark.MVMask( fvec1, kind=1, ml=50 ) # (kind=1 -> motion-compensated , kind=0 -> motion adaptive)
err = Merge( err_bw, err_fw, 0.5 )
diff_spatemp = diff_temp .mt_Merge(diff_spat, err, U=3,V=3)
result = dark .mt_makediff( diff_spatemp, U=3,V=3)
That's pretty basic, and of course one can stuff in lots more things at free will.
After a quick glance through the paper, there are a few points ... they don't use mo-comp at all, the method is 'only' motion-adaptive. Temporal-Bilateral and Volumetric-Bilateral ... well, those we don't have in Avisynth. At least Temporal-Bilateral could be self-cooked with ttempsmooth, via pfclip and according masks.
Reminds me, one feature that's missing in MVTools: create vectors on clip A, then exchange compensation with clip B (MVChangeCompensate) and re-derivate SADs from clip B accordingly. Like "MVChangeSAD(vectors, newclip)".
Occasionally, this might become handy ... e.g. for stuff like this here. ;)

there are many articles about phase correlation, could this be improvement when implemented to mvtools? Depan already uses phase-shift.
