Overview
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.
-mMETHOD-
(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'.
-SMIN-
(default: 4).
Set minimum threshold of luma/chroma difference which is treated as noise.
-TERRT[,MAXT]-
(default: 32,255).
-BERRB[,MAXB]-
(default: 32,255).
-IERRI[,MAXI]-
(default: 16,255).
-CERRC[,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.
Releases
Unchanged in 7 releases since Debian 8 (Jessie).
