Smooth:

Between two images, could you tell me where do they overlap, what I mean is where should I place matching points.  see, i am having some problems to stitch some images, dont know if I have to do it in a veritcal or horizontal way.

Or should I position matching points spreading along the image fisheye circle, so they can match  better....  this is the part I dont understand, what I do is to match features of the images, may be a clock, a mirror, a corner of a wall, what are the better features or sides?
