10 fulla [options] input files
11
13 Apply radial or flatfield vignetting correction as well as geometrical
14 radial distortion and transversal chromatic abberation correction.
15 fulla can be used to batch correct a large number of files. Radial dis‐
17 tortion coefficients can be read from a PTLens database (only database
18 version 4.2 is supported).
19 Vignetting correction is done the same way as described in the nona
21 script file documentation. Vignetting correction can be done based on
22 a flatfield or a radial scaling.
23 Vignetting correction by flatfield division:
25 I = I / c, c = flatfield / mean(flatfield)
26 Radial vignetting correction:
28 I = I / c, c = a + b*r^2 + c*r^4 + d*r^6
29 Correct vignetting by addition, rather than by division:
31 I = I + c
32 The radial correction is identical to the one implemented by panotools:
36 r_new = a*r^4 + b*r^3 + c*r^2 + d*r [1]
38 Since transversal chromatic aberations (TCA) leads to differently
40 scaled objects in the red, green and blue channel, it can be corrected
41 by scaling the red and blue channel so that they match the green chan‐
42 nel. Most applications, like Photoshop or Picture Window Pro offer TCA
43 correction by linear scaling. This is equal to varying the d parameter
44 in equation [1].
45 See http://hugin.sf.net/tutorials/tca for a method to determine these
47 parameters.

51 -o output filename
52 Specify the output filename. If more than one input image is
53 given, this string will be used as suffix (default: _corr)
54 -g a:b:c:d
56 Radial distortion coefficient for all channels, (a, b, c, d).
57 By default no correction is done.
58 -b a:b:c:d
60 Radial distortion coefficents for blue channel, (a, b, c, d).
61 this is applied after the global distortion correction(supplied
62 by -g).
63 -r a:b:c:d
65 Radial distortion coefficents for red channel, (a, b, c, d).
66 this is applied after the global distortion correction(supplied
67 by -g).
68 -f filename
70 Filename of the flatfield image. Enables vignetting correction
71 by flatfield division
72 -c a:b:c:d
74 radial vignetting correction by division:
75 -a Correct vignetting by addition, rather than by division I = I +
77 c
78 -p Try to read radial distortion coefficients (usually supplied
80 using -g) from the PTLens database. The environment variable
81 PTLENS_PROFILE should point to the profile.txt file. Since newer
82 version of the PTLens database are incompatible with fulla,
83 download the PTLens database from the hugin sourceforge website
84 instead: http://www.sf.net/projects/hugin
85 -m Manufacturer
87 Camera manufacturer, for PTLens database query. EXIF data inside
88 jpg files is read, if this option is not given
89 -n CameraName
91 Camera name, for PTLens database query. EXIF data inside jpg
92 files is read, if this option is not given.
93 -l LensName
95 Lens name, for PTLens database query. If not specified, a list
96 of possible lenses is displayed
97 -t n Number of threads that should be used during processing
99 -v Verbose execution
101 -h Display help text

106 No bugs known, if you find any, please send a bug report to me. I will
107 try to fix it.
