Stitching photos

Post by JamesGT » Tue Sep 13, 2005 8:10 pm

It would be nice to have the ability to stitch photos together to make a panoramic view.

I have to do this in photoshop, which can be frustrating at times. It would be nice if you could select your images and then have XnView put them together into one image.

I think there should also be a manual option too so you could piece them together without the program using algorithyms to try and match patterns. Sometimes in some photos that doesn't work out too well.

Yes, but it's really difficult to make a good stitching...

I also think that stitching is a very special field. Writing a stitcher from scratch will never compete with the specialized stitchers which do a really excellent job. There's more relevant and important areas for XnView.

I'm a big stitcher fan... absolutely love the huge images stitching creates.

You might try the following free autostitching software. It is by far the best automated tool (as opposed to manual tool such as PanoTools) I have tried and should amaze you the very first time out.

Truly an example of geniuses at work.

Thank you, John, for the link. An idea came to my mind: Why not talk to those stitcher people and try to establish a better interaction between the tools. E.g. you could select several files using XnView and these could be passed to the stitcher. Or the stitcher could be started and opened in the current XnView directory. Not really a full integration, but still some possible improvement.

We have the Adobe Plugins supported by XnView, perhaps there is a Stitcher available (provided by the autostitch people or other companies)?

It always gives me an out of memory message... :( Was trying to stitch two 4 MP images. :( Really needs some better resources handling.

Hmmm... out of memory?

Perhaps checking your memory usage in the options might help.

I have never had a failure with Autostitch. Routinely stitch 20-25 images at 2.5 mb each. Final file sizes exceed 100Mb.

Of course, I have 1 Gb system, so that may be why.

I did as suggested in the readme, lowering from 0.25 GB down to 0.05GB, no help. I have 384 MB RAM.

Anyways, PanoTools with PTAssembler, AutoPano and Enblend seem to work fine for me. :) (Though I cannot compare, unfortunately.)

Me too! For stuff that has to perfect.

However, AutoStitch will take 50 unsorted 2Mb images and produce a draft pano in less than a minute, and with no intervention on my part other than identifying the files.

Perhaps you might try another group of images as a test.

I did not measure the time, but since PTAssembler has the Auto create button, I don't have to do anything else, either. ;)

Well, two standard 4 MP JPEGs...I guess it won't get easier than that. Anyways, too late now. Maybe when a newer version is available. :)

Hi Hacker

Whatever method PTAssembler/PTools uses, I have found its automatic mode is slow and often assembles the pano improperly.

For instance, that 50 (actually 52) image pano I mentioned above took 25 minutes in PTassembler auto mode and was wildly wrong, even though the image to image accuracy was "extremely low".

The autostitch image took less than a minute and stitched accurately, though the horizon was a little wavey. More than satisfactory for a draft, however. I haven't run the full resolution image, yet. That will take more time, obviously. It will be about 26,000 x 7,500 pixels.

PTAssembler is great for manual point placement (and I have been extremely pleased with the results from my manual efforts), but with stitches of very many images manual point placement is impractical unless the image is really extraordinary (ie worth the effort).

Sorry you couldn't get AutoStitch to work. I love it.

Autostich looks impressive.
I didn't find a price however.
For the moment I use The Panorama Factory.
There is a free version, which isn't perfect, but does a decent job.
