NAME
tca_correct - Calculate transverse chromatic aberrationSYNOPSIS
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
