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use CIECAM02 to blend colors; disable with "--no-ciecam"; note that this option will be withdrawn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.
