Hi Carlos, Thanks for your reply. yes, these pictures are taken holding an iPhone 5 without a tripod. I'm developing an internet consumer mobile app. I'm targeting an average consumer so i can't assume that they will use a tripod, but i have a camera module help to minimize the parallax errors. In addition, we have the 3D positions for each image and am wondering if we can feed this information to Hugin to generate a clean, automatic stitching. Any idea?
