NAME

6       align_image_stack - Align overlapping images for HDR or focus stack
7       creation
8

SYNOPSIS

10       align_image_stack [options] input files
11

DESCRIPTION

13       align_image_stack is used for the alignment of slightly misaligned
14       images. When several differently exposed images are taken in the
15       process of creating a High Dynamic Range image, the images are not per‐
16       fectly aligned, and the quality of the HDR image created will suffer
17       from this. align_image_stack uses the tools available to hugin to opti‐
18       mize the roll, pitch and yaw, as well as some parameters of the lens
19       geometry, to align the images
20

OPTIONS

22       Modes of operation:
23
24       -p file
25           Output .pto file (useful for debugging, or further refinement)
26
27       -a prefix
28           Output aligned images as prefix_xxxx.tif
29
30       -o output
31           Align images and merge them to HDR, generate output.hdr
32
33       Modifiers:
34
35       -v  Verbose, print progress messages. Repeat for higher verbosity
36
37       -e  Assume input images are full frame fish eye (default: rectilinear)
38
39       -t num
40           Remove all control points with an error higher than num pixels
41           (default: 3)
42
43       -f HFOV
44           Approximate horizontal field of view of input images, use if EXIF
45           info not complete
46
47       -m  Optimize field of view for all images, except for first. Useful for
48           aligning focus stacks with slightly different magnification.
49
50       -c num
51           Number of control points (per grid) to create between adjacent
52           images (default: 8)
53
54       -l  Assume linear input files
55
56       -s scale
57           Scale down image by 2^scale (default: 1 [2x down-sampling])
58
59       -g gsize
60           Break image into a rectangular grid (gsize x gsize) and attempt to
61           find num control points in each section (default: 5 [5x5 grid])
62
63       -h  Display help summary.
