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.
