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.
