NAMEenfuse - poor man's HDR
SYNOPSISenfuse [,options/] [,--output=IMAGE/] ,INPUT/...
DESCRIPTIONFuse INPUT images into a single IMAGE.
INPUT... are image filenames or response filenames. Response filenames start with an "@" character.
- -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
- 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
- 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- use CIECAM02 to blend colors; disable with "--no-ciecam"; note that this option will be withdrawn in favor of "--blend-colorspace"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
- 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
- weight given to well-exposed pixels (0 <= WEIGHT <= 1); default: 1
- weight given to highly-saturated pixels (0 <= WEIGHT <= 1); default: 0.2
- weight given to pixels in high-contrast neighborhoods (0 <= WEIGHT <= 1); default: 0
- weight given to pixels in high entropy neighborhoods (0 <= WEIGHT <= 1); default: 0
- optimum exposure value, usually the maximum of the weighting function (0 <= OPTIMUM <= 1); default: 0.5
- characteristic width of the weighting function (WIDTH > 0); default: 0.2
- average over all masks; this is the default
- 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
- 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"
- 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"
- use the ICC profile from PROFILE-FILE instead of sRGB
- 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;
- set one or more KEY-VALUE pairs
Expert fusion options:
- (1st form) select one of the built-in exposure WEIGHT-FUNCTIONs: "gaussian", "lorentzian", "half-sine", "full-sine", or "bi-square"; default: "gaussian"
- (2nd form) load user-defined exposure weight function SYMBOL from SHARED-OBJECT and optionally pass ARGUMENTs
- 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
- set window SIZE for local-contrast analysis (SIZE >= 3); default: 5
- 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
- minimum CURVATURE for an edge to qualify; append "%" for relative values; default: 0
- 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"
- set window SIZE for local entropy analysis (SIZE >= 3); default: 3
- 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%
- -h, --help
- print this help message and exit
- -V, --version
- output version information and exit
- show all globbing algorithms
- show all recognized image formats and their filename extensions
- show who compiled the binary when and on which machine
- show the software components with which Enfuse was compiled
Enfuse accepts arguments to any option in uppercase as well as in lowercase letters.
- 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.
- The OMP_DYNAMIC environment variable controls dynamic adjustment of the number of threads to use in executing OpenMP parallel regions.
