tca_correct1
Calculate transverse chromatic aberration
Usage
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
Overview
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
