NAME
yuvycsnoise - Noise filter specialized for NTSC Y/C separation noise
SYNOPSIS
yuvycsnoise [-t] [-m t|b|i|c] [-S MIN] [-T ERRT[,MAXT]] [-B ERRB[,MAXB]] [-I ERRI[,MAXI]]
[-C ERRC[,MAXC]]
DESCRIPTION
If video capture hardware has only a poor Y/C separator, at vertical stripe (especially
red/blue), noises appear which seem checker flag and bright/dark invert per 1 frame.
yuvycsnoise reduces noises of this type.
OPTIONS
yuvycsnoise accepts the following options:
-t test. Instead of noise reduction, noises will be marked as black pixel.
-m METHOD
(default: tbic).
Select method. METHOD is string in which each character mean method.
t: 'triframe' method of luma noise reduction.
b: 'biframe' method of luma noise reduction.
i: 'infield' method of luma noise reduction.
c: chroma noise reduction. use 3 frames as 'triframe'.
-S MIN (default: 4).
Set minimum threshold of luma/chroma difference which is treated as noise.
-T ERRT[,MAXT]
(default: 32,255).
-B ERRB[,MAXB]
(default: 32,255).
-I ERRI[,MAXI]
(default: 16,255).
-C ERRC[,MAXC]
(default: 12,255).
Set threshold of luma/chroma difference of each methods. ERRx is maximum error of
luma/chroma of pixels around target pixel, which should be same if target contain
noise. MAXx is maximum threshold of luma/chroma difference of target pixel from
luma/chroma after noise reduced.
