ALIGN_IMAGE_STACK(1) HUGIN ALIGN_IMAGE_STACK(1)NAMEalign_image_stack - Align overlapping images for HDR or focus stack
creation
SYNOPSISalign_image_stack [options] input files
DESCRIPTIONalign_image_stack is used for the alignment of slightly misaligned
images or for the registration of a stereo images pair. 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.
-d Optimize radial distortion for all images, except for first.
-i Optimize image center shift for all images, except for first.
-S Assume stereo images - allow horizontal shift of control points.
-A Align stereo window - assumes -S
-P Align stereo window with pop-out effect - assumes -S
-C Auto crop the image to the area covered by all images
-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.
