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.
