Topic: A New Version of Microsoft ICE

Good afternoon, all,

I noticed earlier today that the ICE team at Microsoft Research had written a new weblog entry about their latest version of ICE. It supports stitching panoramas from videos, cleaner blending along the seams of photos, and a few other handy features. Read all about it here: http://bit.ly/icevideo

Very cool, this I'm going to have to try!

Also of note:

Ability to change where ICE keeps the TEMP files!
Ability to cap ICE's RAM usage
Gigapan Support! (What do they mean?  (:  )
Multi-core support/improvements?

It looks to be a pretty solid upgrade; testing now!

Thanks for alerting us to it, Nathanael

No problemo.

I'm thinking that the 'Additional Features' on the ICE homepage (like structured panos from GigaPans) are things that existed in previous releases (though I can't say there hasn't been improvements in this release). =)

Support within the app for customizing the TEMP location is nice, I suppose, though you can customize Windows' TEMP location yourself quite easily, as well (and have been able to for years) which will work for anything that calls it (Photosynth, for example).
Here's a little tutorial: http://getsatisfaction.com/livelabs/topics/photosynth_ran_out_of_disk_space#reply_643231

For previous versions of ICE, you could also define a new environment variable called ICE_CACHE_LOCATION and define its location wherever you wanted, though just having a menu in the program is, as you say, better.

Ha, great continuation of that idea, Nathanael.  Your outline here is very helpful, for being able to control one's TEMP files is terribly important for doing anything substantial with these tools (not to mention Josh Harle and company's 3D Modeling approaches!)

On v1.4.3:

OK, so I've tested one dataset using both versions, and I have noticed some real improvement in the quality of the rendering between version 1.3.x and 1.4.3.  I did not, however, upload the v1.3.x file to Photosynth.net, however, and, therefore, when I cannot do so, given that I updated to v.1.4.3.

Nonetheless, let me just say that in the following v1.4.3 panorama, the entire top of T-Hall did not turn out correctly in v1.3.x, whereas now it is perfect:

Unfortunately, I do not have the time to compare the two versions more directly in the short-term.  I can, however, offer my "dataset," i.e. photographs, to whomever would be interested in carrying out some interesting work in this area.  Processing photos for these various photo integrators (Photosynth, ICE, PMVS, etc) is a very important step that I do not pretend to be the best at in the world.  Shooting and project management are my things.  Let me know, people-who-want-to-use-my-files, and I will most likely oblige you , so long that you agree to share your results and what you learn with me (:

If you have any datasets for 3D reconstruction, there's a section of the Photogrammetry Forum dedicated to them: http://bit.ly/pgrammetrydatasets
Perhaps the photo downloading in http://bit.ly/photosynth-toolkit makes this a bit obsolete, given properly Creative Commons-licensed photos in a synth, but I think it's good to know about nonetheless.

If you know of any similar existing resource for panoramas (sort of a stock image sets for panorama stitching), please let me know. I also asked the ICE forum to tell me about something like this here: http://community.research.microsoft.com/forums/p/6833/12137.aspx#12137 so you may want to watch there for follow-up replies. It would be great to organize this sort of resource and contribute to existing sites if they exist.

Here's a test video pano my wife did in HD (38sec) with her Lumix FZ35 camera http://photosynth.net/view.aspx?cid=9915bdda-afca-4f49-916f-14ca310bf9d5 unfortunately the Lumix shoots in MTS format which Ice doesn't accept so I had to change it to an AVI.  I can say the quality is much lower and you need to take your time videoing. My test looked like crap because I rushed it while trying multiple passes at different angles.

It would of been nice if Ice would have said which video formats it accepts instead of trail and error.

Matt U, from the ICE team, replied about what video formats are supported here: http://community.research.microsoft.com/forums/p/6799/12126.aspx#12126 and also pointed me to these links for more information: http://msdn.microsoft.com/en-us/library/dd757927(v=VS.85).aspx http://en.wikipedia.org/wiki/Media_Foundation

I have some still-photography examples while using v1.4.3 of ICE;  
they are on the bottom of this iNveridux blog-post:

Once again, I am *very* pleased with the results, but the bump in quality could also be a result of my increasing understanding of my capture system, the Gigapan Epic 100.

Nathanael, you'll want to see some of my cooler synths on that post as well, as well as my "Delicate Arch" post, which shows the type of thing you've always talked about but on an iconic landmark:
