This is GlobMoeSt 0.0.6 "of the year" - Global Motion Estimation
Copyright (C) 2005 by Arne Bochem

Usage: globmoest -o OUTFILE [OPTION]... [--] FRAME FRAME...

Required arguments:
  -o FILE        --output FILE            Output result to file named FILE

General options:
  -h             --help                   Output this help
  -q             --quiet                  Make globmoest shut up
  --                                      Tells globmoest to treat all further
                                          arguments as input filenames
  -bg RRGGBB     --background RRGGBB      Color for unset pixels
  -cr L:T:R:B    --crop L:T:R:B           Crops input frames

Blending modes:
  -b             --blend                  Blends overlapping pixels
  -a             --addonly                Does not change pixels, once set
  -n             --noblend                Overwrites pixels (actually not, it's
                                          addonly with reversed image order)

Motion vector files:
  -s FILE        --savemv FILE            Save motion vectors to FILE
  -l FILE        --loadmv FILE            Load motion vectors from FILE
  -cm            --calc-missing           Prevents failure when loading bad or
                                          insufficient motion vector files

Motion estimation options:
  -x NUM         --xsearch NUM            Set horizontal motion search width
  -y NUM         --ysearch NUM            Set vertical motion search width
  -c R:G:B:Y:U:V --coeff R:G:B:Y:U:V      Use specified coefficients in
                                          difference function

Default values:
  --addonly --xsearch 128 --ysearch 128 --coeff 1:1:1:0:0:0 --crop 0:0:0:0
  This is most probably quite slow. You might want to lower xsearch and ysearch

Notation:
  R:G:B:Y:U:V means the coefficients used in the difference function. Must be
              positive (or zero) and R+G+B+Y+U+V must be greater than zero
  L:T:R:B     means L pixels from the left, T from the top, R from the right,
              and B from the bottom (positive or zero)
  RRGGBB      means the hexadecimal representation of a color
  FRAME       means the filename of an image containing one of the input frames
  FILE        means a general filename
  NUM         means a positive (or zero) integer value

Notes:
  - Saving as .png makes unset pixels transparent (without transparency unset
    pixels are whatever you specified as the background color)
  - Setting other coefficients influences the difference function. With the
    coefficients R, G, B, Y, U, V the difference function will calculate:
      pixel difference := (R * |r1 - r2| + ... + V * |v1 - v2|) / (R+G+B+Y+U+V)
    Thus using 0:0:0:1:0:0 would calculate only the luma difference.
  - Setting more coefficients to 0 speeds up motion vector calculation, but
    will probably reduce accuracy in most cases.
  - A non-obvious use for --crop, might be speeding up motion vector calculation
    in combination with -s and -l

Example:
  globmoest -o my_pan.png --noblend --xsearch 32 --ysearch 32 1.png 2.tga 3.jpg
