Perhaps another option "keep only n most widely separated CPs"

After all, the goodness of a c.p. does change after optimization, so eliminating the worst CPs tends to justify what the optimizer does, it doesn't make the best solution.

With my panohead (Manfrotto 303sph) the bottom of the panohead and some of the tripod are in each of the bottom row images. (5D + Sigma 12-24 = 111 degree vertical fov) So the if only the bottom row is used, I may get a good pano of the pano-head, but not the room :-) The algorithm for my pano head ...

The problem with running the geometry analyzer after initial detection is that one or more pictures may not be in the right place, or may not be linked at all. I think we need a manual step to verify that all the images are in about the right place.

HDR layers, multiple exposure layers

One use of Autopano is for architecture, specifically taking pictures of rooms. The problem here is that you can come up with a good exposure for the room, and use +2, 0, -2 bracketing to get a good exposure of the inside. But the windows are blown (think of a dark room and a bright day). Or you can...

There was a thread or two about weighting the center pixels more because the lens is sharper there, and another thread about preferring the pixels from an image shot at 300mm to one shot at 24mm (the 24mm was a guide to help line up the 300mm photos). I think this is another reason to give some pixe...

New kind of layer wanted

One person I know wants pano's taken by taking each image at proper exposure, so if you don't change ISO or aperture, you'll see a bunch of different shutter speeds that make up a layer. He then wants lights and windows taken to properly expose the light or window. Also, if there's more than a stop ...

PtGui`s panorama editor is just as good in my opinion, but they are basically the same. Anything like this in Hugin ? Forgot about that. Been using APP exclusively since 1.3.

']Yes, a more visual approach will appeal to most users. An Image Placement Editor is needed, where you can drag images into place, then easily link them. Rotating is maybe too much and proper CPs placement should eliminate the need for that. Please try Realviz Stitcher (there's a free demo!) to se...

Some thoughts: 1. if you buy on-line, check www.resellerratings.com before you buy. At least one store mentioned here didn't have a great rating. 2. Canon has anti-dust technology, the anti-shake is in the lens (if its there at all) and can be turned off. 3. IIRC, Nikon stated that they see no need ...

I like the drag, drop, and rotate and by default leave it relative to the center points of the images that overlap it, especially if you had a minimum for the overlap--if some images have less than (for example) a 5% overlap, they can be discounted. I would like an option to do a sort of "local geom...

layers, make blown out area transparent

I'd like an option to make blown out outareas transparant when rendering, and a way to select what is "blown out"--it may be best to allow the user to set the value that is the boundary between normal and blown out (e.g. I may want to set 250 out of 255 as the threshold). Also, I'd like to be able t...

Using CPs from one image on another may not be a good idea, The head may have some movement in it, it may be handheld, etc. APP does line up freatures from one photo to the features on another rather than blindly assuming one photo is taken from exaclty the same spot as another.

HDR rendering support

When creating HDR panos, we use several layers, each with its own EV. But the more layers, the more CPs, and its not just a simple multiple of the number of CPs in one layer by the number of layers, it is more akin to the way the number of connections in network grows: with 2 CPs theri is one link o...

I'm pretty sure, it's the inverse that should be implemented : more points on the edge and less in the center. It comes from the fact that the lens has a radial distortion. Having CP near the center doesn't give good candidates for the lens distortion calculation. The farest from they are, the best...

Agreed with kankkarl. Alexander, could you explain a bit about the control point weighting algorithm? For example, Bo mentioned above that he adds more CPs to a specific feature so that feature ends up being 'weighted' more in the optimization process. This seems intuitively correct, but it would b...

OK, the link cleaner is a good idea, but IMO it should apply to geometric analysis also--APP knows beforehand the distance between two images, and shouldn't waste time calculating a link that will later be cleaned. Angular distance is better, the linear distance is distorted on the spherical panos. ...

You could probably simulate this last case pretty well, right now, if you can use UNC paths in the .pano file and then remote desktop over to the rendering computer and add jobs by directly opening .pano files (across the network to the originating computer) in the batch-renderer, but have the pano...
