 MiniDeen is a spatial denoising filter. It replaces every pixel with the average of its neighbourhood.
 
 This is a dual interface port of the [VapourSynth plugin MiniDeen](https://github.com/dubhater/vapoursynth-minideen) version beta 2.
 
+SSE2 is required to run optimized routine. AVX2 routine is also available. Unlike VapourSynth-MiniDeen, this filter returns binary identical result between SIMD and C routine, and SIMD routine does not call C routine for pixels close to frame border.
 
 ## Usage
 
-```
+```python
+# AviSynth+
 LoadPlugin("MiniDeen.dll")
-MiniDeen(clip, radius=1, thrY=10, thrUV=12, Y=3, U=3, V=3)
+MiniDeen(clip, radiusY=1, radiusUV=1, thrY=10, thrUV=12, y=3, u=3, v=3)
+# VapourSynth
+core.neo_minideen.MiniDeen(clip, radius=[1,1,1], threshold=[10,12,12], planes=[0,1,2])
