NAME
hugin_stacker - stack overlapping images to a single image
SYNOPSIS
hugin_stacker [options] --mode=STRING images
DESCRIPTION
hugin_stacker acts on a stack of overlapping images and produces a
combined image and/or a set of masked output images.
hugin_stacker is useful for e.g.
• automatic tourist removal (not only tourists, also other moving
objects ;-))
• noise reduction
• visualize movement
• multiplicity
OPTIONS
--mode
Select stack mode:
min|minimum|darkest
Select the darkest pixel.
max|maximum|brightest
Select the brightest pixel.
avg|average|mean
Calculate the mean for each position.
median
Calculate the median for each position.
winsor
Calculate the Winsor trimmed mean for each position. The
parameter can be set with --winsor-trim=NUMBER (default: 0.2).
sigma
Calculate the sigma clipped mean for each position. Fine-tune
with --max-sigma=NUMBER (default: 2) and
--max-iterations=NUMBER (default: 5).
Further parameters
--output=FILE
Set the filename for the output file (if not given final.tif is
used).
--compression=value
Set the compression of the output files. For jpeg files use values
between 0 and 100. For tiff files valid values are: PACKBITS,
DEFLATE, LZW.
--bigtiff
Write output in BigTIFF format (only with TIFF output).
Mask input images
--mask-input
Beside the stacked output hugin_stacker can also mask the input
images (available only for stacking modes median|winsor|clip). This
mode is activated with --mask-input. In this case the stacked image
is first calculated. Then each pixel in each image is checked: if
the value of this pixel differs more then mask sigma * standard
deviation from the mean/median, this pixel is made visible. If it
is in the mentioned range the pixel is masked out.
--mask-sigma=NUMBER
sets the sigma parameter for --mask-input. Default is 2.
--mask-suffix=STRING
Output a separate mask image for each input image named
inputfilenameSTRING. Default value is "_mask".
--multi-layer-output
Output a layered TIFF with the name specified with --output. The
file contains the averaged image as layer 0 and all input images as
additional layers with the mask as described above.
