align_image_stack is a command-line tool available in the development version of hugin to align overlapping images to facilitate HDR creation, Exposure blending and extended Depth of Field images.
Usage
align_image_stack [options] input files
Options: modes of operation
-p file
Output .pto file (useful for debugging, or further refinement)"
-a prefix
Align images, output as prefix_xxxx.tif
-o output
Merge images to HDR, generate output.hdr
Options: modifiers
-v
Verbose, print progress messages
-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 to create between adjacent images (default: 8)
-l
Assume linear input files
-s scale
Scale down image by 2^scale (default: 1 [2x downsampling]). Scaling down images will improve speed at the cost of accuracy.
-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
