I'm a Hugin and panotools newbie. I came across this thread while 
researching image alignment. Would this approach work to align multiple 
equirectangular images, or more specifically, I would be more interested in 
getting horizontal offsets between a particular image and the reference 
image. My use case is automatically aligning 360 panoramas that are taken 
on a periodic basis. The reason I'm mostly interested in determining the 
offset is because I can align the images in the pano viewer by mapping the 
pixel offsets to yaw offsets.

Thanks,
Alek
