VerticalCleaner

Revision as of 16:42, 15 June 2014

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.
VerticalCleanerSSE2.dll	Dynamically linked SSE3 version. [NOT RECOMMENDED]
*VerticalCleanerSSE2.dll is highly recommended as it's considered to be the most compatible and stable.

- AviSynth 2.5.8 or later

- Progressive input only

- Supported color formats: YUY2, YV12

- MSVCR80.DLL

VerticalCleaner (clip, int "mode", bool "planar")

int mode = 2

Modes:

Description of mode 2:

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.

bool planar = false

See SSETools Interleaved2Planar.
