Topic: How do I add more photos to a synth?

My first synth did not use all of the photos I gave it.  How do I add more photos to enchance the links?

Hi Bill, you need to shoot some more photos to get more coverage, that will help to "synth" the photos better.

I undrestand that I need more photos. I can't see how I add them to the ones already there.

Bill, you'll have to create a new synth and delete the old one.  Sorry, we know that it is not ideal.

It's a shame you can't add more photos.  It would be great if an open account was available so people could add more photos of the same place to an open site instead of just one user uploading their own photos.  The most impressive thing about photosynth when I first saw it was when they gathered over 400 photos from the web and added them together. It would become a great social tool if this function was available.  ie have an open section where you can add photos according to site eg statue of liberty.  Then we could create an impressive display as a collective movement.  Here endith the rant.

I Agree if I had some photos of a location I would like to be able to add mine to someone else's Synth

I think we all want this. There are two problems that the Photosynth team faces: a legal one and a technical one.

Legal: Photos are intellectual property and something that people are quite touchy about. How do you handle things when suddenly one or more of the people who contributed photos to a group synth suddenly decide that they don't want their images to be used in that synth anymore and it breaks the synth for everyone else? I'm sure there are many other considerations as well, but this is the general direction of problems to solve.

Technical: Currently all synthing is done on users' (mine and yours) own computers and then uploaded as one single finished collection. When you want to add more photos to a collection and they are analyzed to fit, they actually affect the position of all other photos that share common features. To add more photos to a synth you would need to download at a minimum:
A) the file that describes where all the current photos have been mapped to in 3D so far
B) 2 Megapixel copies of all images not on your computer so yours can be synthed with them.

Now that adding your new photos to that collection has altered the position of the images that were already online, should their 3D positions in the original synth that they came from be updated since (in theory) the added details that your photos provided should have made their positions more accurate? Should a new synth be formed elsewhere every time that someone adds new photos?

Also, the 'Reconstructing Scene' stage (where the 3D positions of all photos are calculated) is currently still only able to be run on a single core at a time according to a post by Photosynth team member Dan Hou
( http://getsatisfaction.com/livelabs/topics/photosynths_matching_images_is_still_done_on_a_single_core#reply_824157 ).

What this means is that there are serious hurdles to overcome before we'll ever be able to have multiple people from different places in the world all contributing photos to a single synth at the same time. All processing would have to be moved to a central location and the entire set of images would have to be re-analyzed every time new photos were added. There is no way around this. You must compare every photo in a collection to every other photo in that collection.

Trying to solve this in the current distributed manner (I synth the photos I want to add on my own machine and then send the results and new photos back up to the web) would mean that if any other person were currently adding photos to a group synth, I would have to wait for their updated results to be uploaded before I could download that new set of photos and their positions to add my own.

In short, it's not a small problem. :) Like the rest of you, though, I definitely look forward to the day when we get to collaborate and adding new photos looks to we end users like a simple affair.

I'm very new to the site, just found it yesterday, in fact.  I certainly wouldn't mind donating photos to someone else's synth, just to see it work.  Perhaps MSFT could give us a place where we could relinquish copyright over the photos we donate and thus could not retract them later.

For instance, I have tons of photos of Walt Disney World, and many of NYC.  They were not shot overlapping as this didn't exist then.  I'd be happy to donate them even though I am a pro, they were taken for fun, and I certainly don't mind sharing them.

So let's say that one person is doing a synth on WDW, or even just an attraction there, all those interested would donate to, say, Magic Kingdom, or Animal Kingdom, or the resorts, or whatever.  Believe it or not there are many, many people who have not been there, just as I have not been to Italy or Hawaii yet.  What the marvelous syncs do is let people experience these places in breathtaking detail, and I think it is stupendous!

please add the ability to add new photos to a older synth.
Nathanael (Over 1 year ago)
@jokergallagher, Your best bet is to stay tuned to news of Bing's upcoming Read/Write World which will be powered by Windows Azure and is being worked on by some of the top Photosynth team. Here's a some previews: http://bit.ly/readwriteworld

You may also be interested to learn that Photosynth recently moved their entire site to Windows Azure.

That second blog post notes that, "This puts us in a great position to grow our service and add new features and capabilities.", so there's hope.
