yuvycsnoise: Noise filter specialized for NTSC Y/C separation noise

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.
