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.
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.
