NAME

6       tca_correct - Calculate transverse chromatic aberration
7

SYNOPSIS

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

DESCRIPTION

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

OPTIONS

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
