Tracking cilindrical surfaces

Hi every one,

I´ve just started playing around with mocha and getting it to work with AE corner pin solution, which works great! But i´ve only managed to track planar surfaces, i´m getting some trouble trying to track cilindrical surfaces in which i want to place a new image. For instance, i need to replace a couple of ad-banners hanging from the roof of a stadium, these banners follow the path of the stadium´s roof therefore they are curved. How can mocha solve this? i mean, can it be done as if i was tracking a planar surface?

Thanks in advance!
