Ubuntu Manpage: ale - a synthetic capture engine and renderer

NAME

       ale - a synthetic capture engine and renderer

SYNOPSIS

       ale [OPTIONS] original-frame [supplemental-frames ...] output-file

       ale [HELP OPTIONS]

       ale --version

DESCRIPTION

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

EXAMPLES

       ale --hu
           Print the help page on program usage.

       ale 001.ppm 002.ppm 003.ppm out.ppm
           Render output file out.ppm from inputs 001.ppm, 002.ppm, and 003.ppm.

       ale --scale 2 001.ppm 002.ppm 003.ppm out.png
           Render output file out.png at 2x scale.

       ale --perturb-upper=0 --trans-load=a.t --projective frame*.png out.png
           Render output file out.png from inputs frame*.png, using projective transformations as
           described in the file a.t.

       ale --3dv 0 out.png --projective frame*.png null:
           Render output file out.png from inputs frame*.png, using a 3D scene model to determine
           transformations.

       ale --visp last:sinc*lanc:6 sf:0 out/ .jpg in/*.jpg null:
           Render a video stream from files in/*.jpg to the directory out/, stabilizing to the
           first frame, with a lanczos-windowed sinc filter.

USAGE

       ale is a wrapper script that calls the executable ale-bin after extracting exposure EXIF
       information from image files (when the exiftool utility is available) and converting from
       raw formats (when the dcraw utility is available).

       When ale-bin has been linked with ImageMagick, input and output files may be of any kind
       supported by ImageMagick. Otherwise, only PPM files can be read and written by ale-bin.

OPTIONS

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

HELP OPTIONS

       A listing of available help options can be obtained by invoking ale --hu.

ENVIRONMENT

       The wrapper script ale recognizes the following environment variables:

       ALE_BIN
           ALE executable to use.

       DCRAW
           dcraw raw extraction tool to use.

       EXIF_UTILITY
           EXIF extraction utility to use.

       ALE_COUNT_THREADS
           Displays statistics on thread counts when set to a non-zero value.

       PAGER
           Text pager to use (e.g., for displaying help pages).
