yuvycsnoise [-t] [-m t|b|i|c] [-S MIN] [-T ERRT[,MAXT]] [-B ERRB[,MAXB]] [-I ERRI[,MAXI]] [-C ERRC[,MAXC]]
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:
test. Instead of noise reduction, noises will be marked as black pixel.
- -m METHOD
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
Set minimum threshold of luma/chroma difference which is treated as noise.
- -T ERRT[,MAXT]
- -B ERRB[,MAXB]
- -I ERRI[,MAXI]
- -C ERRC[,MAXC]
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.
