ALIGN_IMAGE_STACK(1)
NAME
align_image_stack - Align overlapping images for HDR or focus stack
creation
SYNOPSIS
align_image_stack [options] input files
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 HDR 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
OPTIONS
Modes of operation:
- -p file
- Output .pto file (useful for debugging, or further refinement)
- -a prefix
- Output aligned images as prefix_xxxx.tif
- -o output
- Align images and merge them to HDR, generate output.hdr
- Modifiers:
- -v Verbose, print progress messages. Repeat for higher verbosity
- -e Assume input images are full frame fish eye (default: rectilinear)
- -t num
- Remove all control points with an error higher than num pixels
(default: 3) - -f HFOV
- Approximate horizontal field of view of input images, use if EXIF
info not complete - -m Optimize field of view for all images, except for first. Useful for
- aligning focus stacks with slightly different magnification.
- -c num
- Number of control points (per grid) to create between adjacent
images (default: 8) - -l Assume linear input files
- -s scale
- Scale down image by 2^scale (default: 1 [2x down-sampling])
- -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])
- -h Display help summary.
