Hi,

to make it more concrete: I have circular fisheye images like this one:
http://user.cs.tu-berlin.de/~baumbach/image1.jpg (compressed version)

The idea is to take all images that I have, to correct for the  
fisheye distortion and then take only a center strip from the image  
of about 15 pixel to put them all together in order to have a picture  
like this:
http://user.cs.tu-berlin.de/~baumbach/image2.jpg (compressed version)

I am currently developping a python application to view those  
panoramic images. When you look closely on the top and bottom parts  
of the second image you can see, that there are a lot of artefacts  
that come from the fact, that the source images are distorted. That's  
why I need a way correct those distortions. I don't mind that the  
resulting image won't look correct, since I only use a central strip.

Is that possible with fulla? I just tried to use the parameters from  
Sunnex (parameters b and c) with the following fulla command line:
fulla -v -g 0:-0.2986:0.0671:0 IMG_0711.CR2.tiff
Where comes the horizontal field of view into it?

The result is here:
http://user.cs.tu-berlin.de/~baumbach/image3.jpg (compressed version)
That is not at all what I was looking for.

What am I missing? Does it mean, that the parameters are not working  
with fulla and that I have to calibrate using hugin?

regards,
Hadubard
