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 (de-
fault: 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 be-
tween 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 inputfile-
nameSTRING. 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 addi-
tional layers with the mask as described above.
