NAME

       enfuse - poor man's HDR

SYNOPSIS

       enfuse [options] [--output=IMAGE] INPUT...

DESCRIPTION

       Fuse INPUT images into a single IMAGE.

       INPUT...  are image filenames or response filenames.  Response filenames start with an "@"
       character.

OPTIONS

   Common options:
       -l, --levels=LEVELS
              limit number of blending LEVELS to  use  (1  to  29);  negative  number  of  LEVELS
              decreases maximum; "auto" restores the default automatic maximization

       -o, --output=FILE
              write output to FILE; default: "a.tif"

       -v, --verbose[=LEVEL]
              verbosely report progress; repeat to increase verbosity or directly set to LEVEL

       --compression=COMPRESSION
              set  compression  of  output image to COMPRESSION, where COMPRESSION is: "deflate",
              "jpeg", "lzw", "none", "packbits",  for  TIFF  files  and  0  to  100,  or  "jpeg",
              "jpeg-arith"  for  JPEG  files,  where "jpeg" and "jpeg-arith" accept a compression
              level

   Advanced options:
       --blend-colorspace=COLORSPACE
              force COLORSPACE for blending operations; Enfuse  uses  "CIELUV"  for  images  with
              ICC-profile  and  "IDENTITY"  for  those  without  and  also for all floating-point
              images; other available blend color spaces are "CIELAB" and "CIECAM"

       -c, --ciecam
              use CIECAM02 to blend colors; disable with "--no-ciecam";  note  that  this  option
              will be withdrawn in favor of "--blend-colorspace"

       -d, --depth=DEPTH
              set  the  number of bits per channel of the output image, where DEPTH is "8", "16",
              "32", "r32", or "r64"

       -f WIDTHxHEIGHT[+xXOFFSET+yYOFFSET]
              manually set the size and position of the output  image;  useful  for  cropped  and
              shifted input TIFF images, such as those produced by Nona

       -g     associated-alpha hack for Gimp (before version 2) and Cinepaint

       -w, --wrap[=MODE]
              wrap  around  image  boundary,  where  MODE is "none", "horizontal", "vertical", or
              "both"; default: none; without argument the option selects horizontal wrapping

   Fusion options:
       --exposure-weight=WEIGHT
              weight given to well-exposed pixels (0 <= WEIGHT <= 1); default: 1

       --saturation-weight=WEIGHT
              weight given to highly-saturated pixels (0 <= WEIGHT <= 1); default: 0.2

       --contrast-weight=WEIGHT
              weight given to pixels in high-contrast neighborhoods (0 <= WEIGHT <= 1);  default:
              0

       --entropy-weight=WEIGHT
              weight given to pixels in high entropy neighborhoods (0 <= WEIGHT <= 1); default: 0

       --exposure-optimum=OPTIMUM
              optimum exposure value, usually the maximum of the weighting function (0 <= OPTIMUM
              <= 1); default: 0.5

       --exposure-width=WIDTH
              characteristic width of the weighting function (WIDTH > 0); default: 0.2

       --soft-mask
              average over all masks; this is the default

       --hard-mask
              force hard blend masks and no averaging on finest scale; this is especially  useful
              for focus stacks with thin and high contrast features, but leads to increased noise

   Expert options:
       --save-masks[=SOFT-TEMPLATE[:HARD-TEMPLATE]]
              save  weight masks in SOFT-TEMPLATE and HARD-TEMPLATE; conversion chars: "%i": mask
              index, "%n": mask number, "%p": full path, "%d":  dirname,  "%b":  basename,  "%f":
              filename,  "%e": extension; lowercase characters refer to input images uppercase to
              the output image default: "softmask-%n.tif":"hardmask-%n.tif"

       --load-masks[=SOFT-TEMPLATE[:HARD-TEMPLATE]]
              skip calculation of weight maps  and  use  the  ones  in  the  files  matching  the
              templates  instead.   These  can be either hard or soft masks.  For template syntax
              see "--save-masks"; default: "softmask-%n.tif":"hardmask-%n.tif"

       --fallback-profile=PROFILE-FILE
              use the ICC profile from PROFILE-FILE instead of sRGB

       --layer-selector=ALGORITHM
              set the layer selector ALGORITHM; default: "all-layers"; available algorithms  are:
              "all-layers":  select  all  layers  in  any image; "first-layer": select only first
              layer in each (multi-)layer image; "last-layer": select only  last  layer  in  each
              (multi-)layer  image;  "largest-layer":  select largest layer in each (multi-)layer
              image; "no-layer": do not select any layer from any image;

       --parameter=KEY1[=VALUE1][:KEY2[=VALUE2][:...]]
              set one or more KEY-VALUE pairs

   Expert fusion options:
       --exposure-weight-function=WEIGHT-FUNCTION
              (1st form) select  one  of  the  built-in  exposure  WEIGHT-FUNCTIONs:  "gaussian",
              "lorentzian", "half-sine", "full-sine", or "bi-square"; default: "gaussian"

       --exposure-weight-function=SHARED-OBJECT:SYMBOL[:ARGUMENT[:...]]
              (2nd form) load user-defined exposure weight function SYMBOL from SHARED-OBJECT and
              optionally pass ARGUMENTs

       --exposure-cutoff=LOWERCUTOFF[:UPPERCUTOFF[:LOWERPROJECTOR[:UPPERPROJECTOR]]]
              LOWERCUTOFF and UPPERCUTOFF are the values below  or  above  of  which  pixels  are
              weighted  with  zero  weight  in  exposure weighting; append "%" signs for relative
              values; default: 0%:100%:anti-value:value

       --contrast-window-size=SIZE
              set window SIZE for local-contrast analysis (SIZE >= 3); default: 5

       --contrast-edge-scale=EDGESCALE[:LCESCALE[:LCEFACTOR]]
              set scale on which to look for edges; positive LCESCALE switches on local  contrast
              enhancement  by  LCEFACTOR  (EDGESCALE,  LCESCALE,  LCEFACTOR  >= 0); append "%" to
              LCESCALE for values relative to EDGESCALE; append "%"  to  LCEFACTOR  for  relative
              value; default: 0:0:0

       --contrast-min-curvature=CURVATURE
              minimum  CURVATURE for an edge to qualify; append "%" for relative values; default:
              0

       --gray-projector=PROJECTOR
              apply gray-scale PROJECTOR in exposure or contrast weighing, where PROJECTOR is one
              of "anti-value", "average", "l-star", "lightness", "luminance", "pl-star", "value",
              or "channel-mixer:RED-WEIGHT:GREEN-WEIGHT:BLUE-WEIGHT"; default: "average"

       --entropy-window-size=SIZE
              set window SIZE for local entropy analysis (SIZE >= 3); default: 3

       --entropy-cutoff=LOWERCUTOFF[:UPPERCUTOFF]
              LOWERCUTOFF is the value below of which pixels are treated as black and UPPERCUTOFF
              is  the  value above of which pixels are treated as white in the entropy weighting;
              append "%" signs for relative values; default: 0%:100%

   Information options:
       -h, --help
              print this help message and exit

       -V, --version
              output version information and exit

       --show-globbing-algorithms
              show all globbing algorithms

       --show-image-formats
              show all recognized image formats and their filename extensions

       --show-signature
              show who compiled the binary when and on which machine

       --show-software-components
              show the software components with which Enfuse was compiled

       Enfuse accepts arguments to any option in uppercase as well as in lowercase letters.

ENVIRONMENT

       OMP_NUM_THREADS
              The OMP_NUM_THREADS environment variable sets the  number  of  threads  to  use  in
              OpenMP parallel regions.  If unset Enfuse uses as many threads as there are CPUs.

       OMP_DYNAMIC
              The  OMP_DYNAMIC  environment variable controls dynamic adjustment of the number of
              threads to use in executing OpenMP parallel regions.
