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.
