Okay,
Avisynth:

Mt_AddDiff(Blurred, ReconstructedMedian)

<>
Vapoursynth:

core.std.MergeDiff(Blurred, ReconstructedMedian))

Avisynth:

MT_Luts(Diff, Diff, mode="med", pixels = " 0 0 1 0 -1 0 " ,  expr = " X Y - X Y - X Y - abs 1 + * X Y - abs 1 + "+THR+" 1 >= "+THR+" 0.5 ^ "+THR+" ? + / - 128 +", u=1,v=1)

<>
Vapoursynth:

partial_expr = lambda M, N: f" x x[{M},{N}] - x x[{M},{N}] - x x[{M},{N}] - abs 1 + * x x[{M},{N}] - abs 1 + {THR} 1 >= {thr_s} 0.5 pow {THR} ? + / - 128 + "
medianDiff = core.akarin.Expr(diff, [partial_expr(0,0) + partial_expr(1,0) + partial_expr(-1,0) + "sort3 drop swap drop", ""])

=> But how to convert,
Avisynth

Mt_Convolution(Horizontal=" 1 1 0 0 1 0 0 1 1 ", vertical = " 1 ", u=1, v=1)

to Vapoursynth?
