Let b1, b2, c, t1, t2 be a vertical sequence of pixels. The center pixel c is to be modified in terms of the 4 neighbours. For simplicity let us assume that b2 <= t1. Then in mode 1, c is clipped with respect to b2 and t1, i.e. c is replaced by max(b2, min(c, t1)). In mode 2 the clipping intervall is widened, i.e. mode 2 is more conservative than mode 1. If b2 > b1 and t1 > t2, then c is replaced by max(b2, min(c, max(t1,d1) )), where d1 = min(b2 + (b2 - b1), t1 + (t1 - t2)). In other words, only if the gradient towards the center is positive on both clipping ends, then the upper clipping bound may be larger. | Let b1, b2, c, t1, t2 be a vertical sequence of pixels.

[edit] Description
A fast vertical median plugin which comes in 4 versions:
Name Comments VerticalCleanerS.dll Statically linked SSE version. VerticalCleaner.dll Dynamically linked SSE version. VerticalCleanerSSE2.dll Dynamically linked SSE2 version. VerticalCleanerSSE3.dll Dynamically linked SSE3 version. [NOT RECOMMENDED] *VerticalCleanerSSE2.dll is highly recommended as it's considered to be the most compatible and stable.
Note: RgTools is recommended as a modern drop-in replacement for VerticalCleaner.
[edit] Requirements
- AviSynth 2.5.8 or later
- Progressive input only
- Supported color formats: YUY2, YV12

[edit] Syntax and Parameters
- VerticalCleaner (clip, int "mode", bool "planar")
- clip =
- Input clip.
- clip =

[edit] Mode Description
Written by Kassandro
Let b1, b2, c, t1, t2 be a vertical sequence of pixels. The center pixel c is to be modified in terms of the 4 neighbours. For simplicity let us assume that b2 <= t1. Then in mode 1, c is clipped with respect to b2 and t1, i.e. c is replaced by max(b2, min(c, t1)). In mode 2 the clipping intervall is widened, i.e. mode 2 is more conservative than mode 1. If b2 > b1 and t1 > t2, then c is replaced by max(b2, min(c, max(t1,d1) )), where d1 = min(b2 + (b2 - b1), t1 + (t1 - t2)). In other words, only if the gradient towards the center is positive on both clipping ends, then the upper clipping bound may be larger.
If b2 < b1 and t1 < t2, then c is replaced by max(min(b2, d2), min(c, t1)), where d2 = max(b2 - (b1 - b2), t1 - (t2 - t1)). In other words, only if the gradient towards the center is negative on both clipping ends, then the lower clipping bound may be smaller.
In mode 1 the top and the bottom line are always left unchanged. In mode 2 the two first and the two last lines are always left unchanged.
[edit] Examples
VerticalCleaner with default values:
AviSource("Blah.avi") VerticalCleaner(mode=2, planar=false)
