Workaround available for WinXP SP2 out of memory issue.

Photosynth running out of memory? Do you have Windows XP SP2? (Not SP1, not SP3 - just SP2) We have a workaround available for you. All you need to do is install WIC (Windows Imaging Component). There are two options for the install: You can get WIC directly from the Download Center here, for free - but this requires Windows Genuine validation.

An easier way to get WIC is to simply install the latest Windows Live Photo Gallery.

Does the Photosynth generator app switch to an more memory efficient algorithms (provided by WIC, if available), or how does it solve the issue?

I read on this website that all process steps but one are multi-threaded. Is there a likelyhood that the step that consumes most memory is the single threaded one?

And a bit offtopic, maybe someone can mention the involved process steps by name (a bit more technical than the apps progress bar please ;)

Yes, the code prefers WIC for image conversion, if it's present.

This particular bug isn't threading related - I believe it's a memory leak that has been fixed but not yet integrated.

To answer your question about the process, image conversion to the Deep Zoom (Seadragon) tile format happens in parallel to the synth pipeline (feature extraction -> matching -> reconstruction). What you see in the app progress bar follows the latter process, until it is complete - at which time you see progress on file upload. Once both are complete, the synth files need to be processed and unpacked onto the storage servers ("publishing").

I should have also mentioned that upgrading to XP SP3 is really the best way to fix this issue.

Thanks Darius for pointing this out.. :-)
