Hi Carlos, Thanks for your reply. We have additional information on the images than just Hugin. We know the 3D position of each image. Will it help in doing several automatic pre-processing before feeding the information to Hugin?
If you have time, i will greatly appreciate the opportunity to chat with you. Pls let me know your availability and a phone number.
