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.
