NAME
       tca_correct - Calculate transverse chromatic aberration

SYNOPSIS
       tca_correct [options] inputfile

       <inputfile> is the base name of 4 image files:

       <inputfile>
	   Colour file to compute TCA parameters

       red_<inputfile>
	   Red channel of <inputfile>

       green_<inputfile>
	   Green channel of <inputfile>

       blue_<inputfile>
	   Blue	channel	of <inputfile>

       The channel images must be colour images	with 3 identical channels.  If
       any of -R, -G, or -B is given, this file	name is	used instead of	the
       derived name.

       Output: commandline arguments for fulla

DESCRIPTION
       Generates fulla command-line parameters for correction of transverse
       chromatic aberration (TCA) from sample photos. Ideal sample photos
       would have a lot	of contrast over the entire image area,	little
       saturated colour	and no blown highlights.

OPTIONS
       -h  Display help

       -l  input file is PTO file instead of image

       -m method
	   optimization	method (0 normal, 1 newfit)

       -o optvars
	   string of variables to optimize ("abcvde")

       -r  Reset values	(this will zero	a,b,c,d,e params and set v to 10)
	   makes sense only with -l option

       -s _scale>
	   Scale for corner detection

       -n _number>
	   number of points per	grid cell (default: 10)

       -g _number>
	   divide image	in <number>x<number> grid cells	(default: 10)

       -t num
	   Remove all control points with an error higher than num pixels
	   (default: 1.5)

       -v  Verbose

       --save-into-database
	   Saves the tca data into Hugin lens database

       -w filename
	   write PTO file

       -R _r>
	   Use this file as red	channel

       -G _g>
	   Use this file as green channel

       -B _b>
	   Use this file as blue channel
