• Reimplement verticalcleaner
• adjust contrasharpen repair default value to 1 (to match AVS)
• replace usage of ctmf
• remove "compatbility" std.Expr calls where applicable, as they do not always have the same output

Hello,

I tried using vs-dehalo's fine_dehalo but it currently doesn't work, same with YAHR.

Script:
import vapoursynth as vs
from vsdehalo import fine_dehalo
core = vs.core

src = core.d2v.Source(r'sti_01.d2v', rff=False)
src = fine_dehalo(src)
src.set_output()

vsedit:
Failed to evaluate the script:
Python exception: cannot import name 'iterate' from 'vsrgtools.util' (C:\Program Files\Python310\lib\site-packages\vsrgtools\util.py)

Traceback (most recent call last):

ImportError: cannot import name 'iterate' from 'vsrgtools.util' (C:\Program Files\Python310\lib\site-packages\vsrgtools\util.py)

P.S. How do I use vsdehalo's YAHRmask from YAHRmod or YAHR vanilla? What is PlanesT and what does it do?

Kind Regards

Avisynth has a script known as "Soothe" which is basically a very safe temporal soften filter for reducing shimmer introduced by sharpening.

Two new functions that make the diff against a common ref clip instead of their own blurred clip.

Gaussian kernel is non-interpolatory meaning a same-res resample can be performed to create a blur effect, the current function is instead resizing with bilinear and gauss which not only hurts performance but also quality.

Ideally all forms of contrasharpen should be merged into a single function with the following features:

• Allow the user to specify a custom blur function/clip
• Allow the user to specify a custom sharp function/clip
• Allow the switching between Median and absolute difference limiting

With these we can keep the functionality of all the existing contrasharpen functions, but into one universal script instead.
To easily replicate behavior of the old scripts we can make presets for their different approaches to blurring, sharpening, etc.

Have you looked at sekrit's True Gaussian Blur port? I thought it might be useful here: HomeOfVapourSynthEvolution/havsfunc#42

Add ref and alogorithm from the CPU plugin to the vspyplugin cuda BilateralFilter.

Occurs when attempting to pass an anonymous function in diff_merge and lehmer_diff_merge Maybe others.

Add the mean of the lower freq diff

Also make it like diff_merge, and support multiple clips (up to 13)

Instead of using a basic unsharp; we can try CAS: https://github.com/HomeOfVapourSynthEvolution/VapourSynth-CAS
