TCA_CORRECT(1) HUGIN TCA_CORRECT(1)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
-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
