vector quantisation to reduce the size or other methods as well..
Depending how many concentric mosaics are used, the image size can be up
to 150 megs uncompressed using 320x240 basic image resolution.

the 3d information is in the other slits. But I have an idea...
There is a paper of handheld video camera for cm, but it's getting
quite complicated. The structure from motion must be calculated to do
all the corrections and the images are interpolated to ensure even movement.

May I ask why you choose OpenCV? I found this very unstable and buggy
when I used it for some tests.

crashed occasionally, But otherwise I've had no problems with it. And my
great idea of using view morphing to interpolate is readily available
in opencv. Only the number of pictures taken must still be quite high to
create good view morphing, Alexandre's hope to take only 8, doesn't work
at all. (or maybe the view morphing algorithm in opencv is buggy! :-)

Maybe you can debug it and it will work with one normal pano! ;)
I am looking forward to see your app!
When I looked for some more papers I found these two interesting
things. These are recordings of talks at Google so we can imaging what
version >4 of Google Earth will look like.
Photorealistic modeling of large-scale scenes.
Its like an Object Movie++
And Virtual LA
The interesting thing is that both use Photographs as a basis of their
models so I hope you also find it interesting but I am aware that this
is getting a bit OT.
- Hey there,
Did anyone try out the new autopano from autopano.net, claims to do HDR
on the fly. Tried with 8mm lens but didnt quite do the right job, found
out it isnt compatible yet with fisheyes.
Try it out!

camera tilted 34Â° sideways when shooting panos.
Autopano did order them like stairs. It was nice to
look at but not exactly right. Alexandre told me that
fisheye support is coming soon.

- Autopano Pro is currently in the v1.3 branch which aims is to give
some manual tools to correct a panorama. Yesterday, phase 2 of beta 3
was released with many new features. Just have a look here :
We were forced to postpone Fisheyes support before for such lens, you
need more offen a manual mode than for standard lens. That's why we
decided to first release a control point editor in the product before
the activation of fisheye. But fisheye is already working internally,
I just cannot activate them until control point editor is finished. I
just want this feature working for 95% of panorama, that's huge and
needs many finetunning.
