9 tca_correct [options] inputfile
10
11 <inputfile> is the base name of 4 image files:
12
13 <inputfile>
14 Colour file to compute TCA parameters
15
16 red_<inputfile>
17 Red channel of <inputfile>
18
19 green_<inputfile>
20 Green channel of <inputfile>
21
22 blue_<inputfile>
23 Blue channel of <inputfile>
24
25 The channel images must be colour images with 3 identical channels. If
26 any of -R, -G, or -B is given, this file name is used instead of the
27 derived name.
28
29 Output: commandline arguments for fulla
30
32 Generates fulla command-line parameters for correction of transverse
33 chromatic aberration (TCA) from sample photos. Ideal sample photos
34 would have a lot of contrast over the entire image area, little
35 saturated colour and no blown highlights.
36
38 -h Display help
39
40 -l input file is PTO file instead of image
41
42 -m method
43 optimization method (0 normal, 1 newfit)
44
45 -o optvars
46 string of variables to optimize ("abcvde")
47
48 -r Reset values (this will zero a,b,c,d,e params and set v to 10)
49 makes sense only with -l option
50
51 -s <scale>
52 Scale for corner detection
53
54 -n <number>
55 number of points per grid cell (default: 10)
56
57 -g <number>
58 divide image in <number>x<number> grid cells (default: 10)
59
60 -t num
61 Remove all control points with an error higher than num pixels
62 (default: 1.5)
63
64 -v Verbose
65
66 --save-into-database
67 Saves the tca data into Hugin lens database
68
69 -w filename
70 write PTO file
71
72 -R <r>
73 Use this file as red channel
74
75 -G <g>
76 Use this file as green channel
77
78 -B <b>
79 Use this file as blue channel
