Align image stack
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
Optimize radial distortion for all images, except for first.
Optimize image center shift for all images, except for first.
Optimize X coordinate of the camera position.
Optimize Y coordinate of the camera position.
Optimize Z coordinate of the camera position. Useful for aligning more distorted images.
Assume stereo images - allow horizontal shift of control points. Adds all control points as "horizontal lines".
Align stereo window - assumes -S. Adds one "normal" control point that is the nearest point so everything will appear behind the display plane.
Align stereo window with pop-out effect - assumes -S. Adds one "normal" control point that is the nearest point from the border areas so the center of the image may appear in front of the display plane.
Auto crop the image to the area covered by all images.
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] )
