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.

-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
