Code:
original = last
filtered = last.aWarpSharp2(chroma=6)
mt_lutxy(original,filtered, "x y - abs 255 *", u=-128, v=-128)
Warpsharp detects the "exact" edge, and pixels around the edge would move along to the edge by vectors, "guide by luma", that's telling you you are processing chroma planes but you get the vector and edge reference from luma plane
