DESCRIPTION

17       ALE is a free software synthetic capture engine and renderer accepting,
18       as input, a sequence of image frames, and producing, as output,
19       rendered images, registration data, and 3D models (currently
20       experimental).

EXAMPLES

24       ale --hu
25           Print the help page on program usage.
26
27       ale 001.ppm 002.ppm 003.ppm out.ppm
28           Render output file out.ppm from inputs 001.ppm, 002.ppm, and
29           003.ppm.
30
31       ale --scale 2 001.ppm 002.ppm 003.ppm out.png
32           Render output file out.png at 2x scale.
33
34       ale --perturb-upper=0 --trans-load=a.t --projective frame*.png out.png
35           Render output file out.png from inputs frame*.png, using projective
36           transformations as described in the file a.t.
37
38       ale --3dv 0 out.png --projective frame*.png null:
39           Render output file out.png from inputs frame*.png, using a 3D scene
40           model to determine transformations.
41
42       ale --visp last:sinc*lanc:6 sf:0 out/ .jpg in/*.jpg null:
43           Render a video stream from files in/*.jpg to the directory out/,
44           stabilizing to the first frame, with a lanczos-windowed sinc
45           filter.

USAGE

48       ale is a wrapper script that calls the executable ale-bin after
49       extracting exposure EXIF information from image files (when the
50       exiftool utility is available) and converting from raw formats (when
51       the dcraw utility is available).
52
53       When ale-bin has been linked with ImageMagick, input and output files
54       may be of any kind supported by ImageMagick. Otherwise, only PPM files
55       can be read and written by ale-bin.

OPTIONS

59       OPTIONS are summarized via built-in help pages (see HELP OPTIONS
60       below). More detailed manuals describing options and internal
61       algorithms are available for certain versions of ALE. See SEE ALSO
62       below for more details on other manuals.
