7
9 fulla [options] inputfile(s)
10
12 Apply radial or flat-field vignetting correction as well as geometrical
13 radial distortion and transversal chromatic aberration correction.
14
15 fulla can be used to batch correct a large number of files. Radial dis‐
16 tortion coefficients can be read from a PTLens database (only database
17 version 4.2 is supported).
18
19 Vignetting correction is done the same way as described in the nona
20 script file documentation. Vignetting correction can be done based on
21 a flat-field or a radial scaling.
22
23 Vignetting correction by flat-field division:
24 I = I / c, c = flat-field / mean(flat-field)
25
26 Radial vignetting correction:
27 I = I / c, c = a + b*r^2 + c*r^4 + d*r^6
28
29 The radial distortion correction is identical to the one implemented by
30 PanoTools:
31
32 r_new = a*r^4 + b*r^3 + c*r^2 + d*r [1]
33
34 Since transversal chromatic aberrations (TCA) leads to differently
35 scaled objects in the red, green and blue channel, it can be corrected
36 by scaling the red and blue channel so that they match the green chan‐
37 nel. Most applications, like Photoshop or Picture Window Pro offer TCA
38 correction by linear scaling. This is equal to varying the d parameter
39 in equation [1].
40
41 See http://hugin.sf.net/tutorials/tca for a method to determine these
42 parameters.
43
45 -g a:b:c:d
46 Radial distortion coefficient for all channels, (a, b, c, d)
47
48 -b a:b:c:d
49 Radial distortion coefficients for blue channel, (a, b, c, d). This
50 is applied on top of the -g distortion coefficients, use for TCA
51 corr
52
53 -r a:b:c:d
54 Radial distortion coefficients for red channel, (a, b, c, d). This
55 is applied on top of the -g distortion coefficients, use for TCA
56 corr
57
58 -p Try to read radial distortion coefficients (usually supplied using
59 -g) from the PTLens database. The environment variable PTLENS_PRO‐
60 FILE should point to the profile.txt file. Since newer version of
61 the PTLens database are incompatible with fulla, download the
62 PTLens database from the hugin sourceforge website instead:
63 http://www.sf.net/projects/hugin
64
65 -m Canon
66 Camera manufacturer, for PTLens database query. EXIF data inside
67 JPEG files is read, if this option is not given
68
69 -n Camera
70 Camera name, for PTLens database query. EXIF data inside JPEG files
71 is read, if this option is not given.
72
73 -l Lens
74 Lens name, for PTLens database query if not specified, a list of
75 possible lenses is displayed
76
77 -d 50
78 Specify focal length in mm, for PTLens database query. EXIF data
79 inside JPEG files is read, if this option is not given.
80
81 -s Do not rescale the image to avoid black borders.
82
83 -f filename
84 Vignetting correction by flat-field division
85
86 I = I / c, c = flat-field / mean(flat-field)
87
88 -c a:b:c:d
89 Radial vignetting correction by division:
90
91 I = I / c, c = a + b*r^2 + c*r^4 + d*r^6
92
93 -i value
94 Gamma of input data. used for gamma correction before and after
95 flat-field correction
96
97 -t n
98 Number of threads that should be used during processing
99
100 -h Display help summary.
101
102 -o name
103 Set output filename. If more than one image is given, the name will
104 be uses as suffix (default suffix: _corr)
105
106 -e value
107 Compression of the output files
108
109 For JPEG output: 0-100
110 For tiff output: DEFLATE, LZW
