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.
