align_image_stack [options] input files
Options: modes of operation
Output .pto file (useful for debugging, or further refinement)"
Align images, output as prefix_xxxx.tif
Merge images to HDR, generate output.hdr
Verbose, print progress messages
Remove all control points with an error higher than num pixels (default: 3)
Optimize field of view for all images, except for first. Useful for aligning focus stacks with slightly different magnification
Number of control points to create between adjacent images (default: 8)
Assume linear input files
Scale down image by 2^scale (default: 1 [2x downsampling]). Scaling down images will improve speed at the cost of accuracy.
Break image into a rectangular grid (gsize x gsize) and attempt to find num control points in each section (default: 5 [5x5 grid] )
