.IX Title "ALIGN_IMAGE_STACK 1"
.TH ALIGN_IMAGE_STACK 1 "2009-05-07" "perl v5.8.5" "HUGIN"
.SH "NAME"
align_image_stack \- Align overlapping images for HDR or focus stack creation
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\fBalign_image_stack\fR [options] \fIinput files\fR
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
align_image_stack is used for the alignment of slightly misaligned images. When several
differently exposed images are taken in the process of creating a High Dynamic Range
image, the images are not perfectly aligned, and the quality of the \s-1HDR\s0 image created
will suffer from this. align_image_stack uses the tools available to hugin to optimize
the roll, pitch and yaw, as well as some parameters of the lens geometry, to align the
images
.SH "OPTIONS"
.IX Header "OPTIONS"
Modes of operation:
.IP "\fB\-p\fR \fIfile\fR" 4
.IX Item "-p file"
Output .pto file (useful for debugging, or further refinement)
.IP "\fB\-a\fR \fIprefix\fR" 4
.IX Item "-a prefix"
Output aligned images as prefix_xxxx.tif
.IP "\fB\-o\fR \fIoutput\fR" 4
.IX Item "-o output"
Align images and merge them to \s-1HDR\s0, generate output.hdr
.PP
Modifiers:
.IP "\fB\-v\fR" 4
.IX Item "-v"
Verbose, print progress messages. Repeat for higher verbosity
.IP "\fB\-e\fR" 4
.IX Item "-e"
Assume input images are full frame fish eye (default: rectilinear)
.IP "\fB\-t\fR \fInum\fR" 4
.IX Item "-t num"
Remove all control points with an error higher than num pixels
(default: 3)
.IP "\fB\-f\fR \fI\s-1HFOV\s0\fR" 4
.IX Item "-f HFOV"
Approximate horizontal field of view of input images, use if \s-1EXIF\s0 info
not complete
.IP "\fB\-m\fR" 4
.IX Item "-m"
Optimize field of view for all images, except for first. Useful for
aligning focus stacks with slightly different magnification.
.IP "\fB\-c\fR \fInum\fR" 4
.IX Item "-c num"
Number of control points (per grid) to create between adjacent images
(default: 8)
.IP "\fB\-l\fR" 4
.IX Item "-l"
Assume linear input files
.IP "\fB\-s\fR \fIscale\fR" 4
.IX Item "-s scale"
Scale down image by 2^scale (default: 1 [2x down\-sampling])
.IP "\fB\-g\fR \fIgsize\fR" 4
.IX Item "-g gsize"
Break image into a rectangular grid (gsize x gsize) and attempt to
find num control points in each section (default: 5 [5x5 grid])
.IP "\fB\-h\fR" 4
.IX Item "-h"
Display help summary.
