.SH NAME
enfuse \- poor man's HDR
.SH SYNOPSIS
.B enfuse
[\fIoptions\fR] [\fI--output=IMAGE\fR] \fIINPUT\fR...
.SH DESCRIPTION
Fuse INPUT images into a single IMAGE.
.PP
INPUT... are image filenames or response filenames.  Response
filenames start with an "@" character.
.SS "Common options:"
.TP
\fB\-V\fR, \fB\-\-version\fR
output version information and exit
.TP
\fB\-h\fR, \fB\-\-help\fR
print this help message and exit
.TP
\fB\-l\fR, \fB\-\-levels\fR=\fILEVELS\fR
number of blending LEVELS to use (1 to 29);
negative number of LEVELS decreases maximum
.TP
\fB\-o\fR, \fB\-\-output\fR=\fIFILE\fR
write output to FILE; default: "a.tif"
.TP
\fB\-v\fR, \fB\-\-verbose\fR[=\fILEVEL\fR]
verbosely report progress; repeat to
increase verbosity or directly set to LEVEL
.TP
\fB\-w\fR, \fB\-\-wrap\fR[=\fIMODE\fR]
wrap around image boundary, where MODE is
NONE, HORIZONTAL, VERTICAL, or BOTH; default: none;
.TP
\fB\-\-compression\fR=\fICOMPRESSION\fR
set compression of output image to COMPRESSION,
where COMPRESSION is:
NONE, PACKBITS, LZW, DEFLATE for TIFF files and
0 to 100 for JPEG files
.SS "Extended options:"
.TP
\fB\-b\fR BLOCKSIZE
image cache BLOCKSIZE in kilobytes; default: 2048KB
.TP
\fB\-c\fR
use CIECAM02 to blend colors
.TP
\fB\-d\fR, \fB\-\-depth\fR=\fIDEPTH\fR
set the number of bits per channel of the output
image, where DEPTH is 8, 16, 32, r32, or r64
.TP
\fB\-g\fR
associated\-alpha hack for Gimp (before version 2)
and Cinepaint
.TP
\fB\-f\fR 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
.TP
\fB\-m\fR CACHESIZE
set image CACHESIZE in megabytes; default: 1024MB
.SS "Fusion options:"
.TP
\fB\-\-exposure\-weight\fR=\fIWEIGHT\fR
weight given to well\-exposed pixels
(0 <= WEIGHT <= 1); default: 1
.TP
\fB\-\-saturation\-weight\fR=\fIWEIGHT\fR
weight given to highly\-saturated pixels
(0 <= WEIGHT <= 1); default: 0.2
.TP
\fB\-\-contrast\-weight\fR=\fIWEIGHT\fR
weight given to pixels in high\-contrast neighborhoods
(0 <= WEIGHT <= 1); default: 0
.TP
\fB\-\-entropy\-weight\fR=\fIWEIGHT\fR
weight given to pixels in high entropy neighborhoods
(0 <= WEIGHT <= 1); default: 0
.TP
\fB\-\-exposure\-mu\fR=\fIMEAN\fR
center also known as MEAN of Gaussian weighting
function (0 <= MEAN <= 1); default: 0.5
.TP
\fB\-\-exposure\-sigma\fR=\fISIGMA\fR standard deviation of Gaussian weighting
function (SIGMA > 0); default: 0.2
.TP
\fB\-\-soft\-mask\fR
average over all masks; this is the default
.TP
\fB\-\-hard\-mask\fR
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
.SS "Expert options:"
.TP
\fB\-\-contrast\-window\-size\fR=\fISIZE\fR
set window SIZE for local\-contrast analysis
(SIZE >= 3); default: 5
.TP
\fB\-\-gray\-projector\fR=\fIOPERATOR\fR
apply gray\-scale projection OPERATOR in exposure
or contrast weighing, where OPERATOR is one of
"average", "l\-star", "lightness", "value",
"luminance", or
"channel\-mixer:RED\-WEIGHT:GREEN\-WEIGHT:BLUE\-WEIGHT";
default: "average"
.TP
\fB\-\-contrast\-edge\-scale\fR=\fIEDGESCALE[\fR: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; defaults: 0:0:0
.TP
\fB\-\-contrast\-min\-curvature\fR=\fICURVATURE\fR
minimum CURVATURE for an edge to qualify; append
"%" for relative values; default: 0
.TP
\fB\-\-entropy\-window\-size\fR=\fISIZE\fR
set window SIZE for local entropy analysis
(SIZE >= 3); default: 3
.TP
\fB\-\-entropy\-cutoff\fR=\fILOWERCUTOFF[\fR: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%
.TP
\fB\-\-save\-masks[\fR=\fISOFT\-TEMPLATE[\fR: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"
