Vapoursynth-ATWT
Vapoursynth-ATWT is a VapourSynth plugin that implements the À Trous Wavelet Transform for frequency separation. It decomposes a video clip into multiple frequency layers (Detail) and a residual layer (Base).
Installation
pip install vapoursynth-atwt
Core Plugin API
The plugin exports two low-level functions.
atwt.ExtractFrequency(clip, radius=1)
Extracts a detail layer from the input clip.
- Formula: $Detail = Src - Blur(Src)$
- clip: Input clip.
- radius: The dilation factor of the wavelet kernel. Step size = $2^{(radius-1)}$. Default is 1.
atwt.ReplaceFrequency(base, detail)
Recombines a base layer with a detail layer.
- Formula: $Output = Base + (Detail - Neutral)$
- base: The low-frequency clip.
- detail: The high-frequency clip (result from
ExtractFrequency). - Note: This function automatically handles neutral grey offsets for integer formats.
Python Helper Scripts
To modify specific levels, one cannot simply call ExtractFrequency(radius=2) on the source, as that would include Level 1 details as well. One must peel the layers recursively.
import vapoursynth as vs
core = vs.core
def atwt_decompose(clip: vs.VideoNode, levels: int = 2) -> list[vs.VideoNode]:
"""
[Level_1, Level_2, ..., Level_N, Base(Residual)]
layers[0] -> Level 1
layers[1] -> Level 2
layers[-1] -> Base
"""
details = []
current_base = clip
for i in range(1, levels + 1):
d = core.atwt.ExtractFrequency(current_base, radius=i)
next_base = core.std.MakeDiff(current_base, d)
details.append(d)
current_base = next_base
return details + [current_base]
def atwt_recombine(layers: list[vs.VideoNode]) -> vs.VideoNode:
current_clip = layers[-1]
details_reversed = layers[:-1][::-1]
for detail in details_reversed:
current_clip = core.atwt.ReplaceFrequency(base=current_clip, detail=detail)
return current_clip
Compilation
A C++23-compatible compiler is required.
python -m pip install build
