Image stitching software?

Post Sat Dec 03, 2005 10:57 am


Hi,

I have about 150 gif images (all exactly the same size, colours, etc), and I need them all stitched together without any borders or anything in between. The images are named xx.y.gif - xx and y are the positions the images are supposed to be in in the final image.

Does anyone know of any software that can automate this? I did it manually last time and it was pretty painful :)

Thanks

If you mean without any overlap, it's much easier than if there is overlap between the contents of the images that requires careful placement. For the harder case of overlapping images, check out http://www.panoramafactory.com and hugin.sourceforge.net (the latter is open source, but I prefer -- and have registered -- the former).

To simply place images next to each other in a new file, try IrfanView (http://www.irfanview.com) or the 'montage' command in ImageMagick (http://www.imagemagick.org). Both programs are free.

Cheers :)

Ifranview worked fine for the vertical strips, but when I try to join those strips together it gets 2 or 3 strips across and stops. It saves the image fine, there are no error messages, but the output is much smaller than I'd expect.

Off to try ImageMagick :)

Edit: ImageMagick complains that some of my images are corrupt. This could be because of the size of them (images are 2600*2600, 10 down in a strip, 15 strips across).

Are there any other programs that will allow me to do this? I tried Paint as a last resort, and it won't let me have an image that large :P

never tried if it can stitch that much photos, but Autostitch is usually doing a great job - link on top of my gallery:

if it does not work with all photos at once, maybe you can do a few panos and stich them together again

When you stitch images with Irfan, you have to tell it the final size of the image you want. With the numbers you have, at 100%, it would be 26,000 X 39,000.

Memory could be another problem with such a big image. Make sure you have enough RAM to handle such a big project.

Have to say I have used panorama factory for several years... It is the best stitching software I have found.

Have a look at

I'm not surprised that you're running into size issues -- you're asking to create a 3GB image (26000x39000 pixels = 1,014,000,000 pixels, times 3 bytes per pixel = 3,042,000,000 bytes). Does the final file truly need to be that size, or would it be acceptable to cut the dimensions in half, to 13000x19500? That's still 750 megs before compression, but should be doable.

Also, JPEG format may only allow 32767 pixels in either dimension (as I seem to dimly recall).

PS. I definitely second bobclewley's opinion of Panorama Factory, and the new version 4 is an amazing advance when it comes to dealing with tilted or rotated images -- http://www.pbase.com/image/53372471 is a fully-automatic stitch of pictures taken handheld from a rocking boat.

Thanks for all the tips. What I am trying to stitch together are map images (which are perfectly aligned to simply placing them together will do the trick). I can't really reduce the quality, as that will make a lot of the smaller roads and roadnames too blurry.

I can try splitting it into 2 images though, and just having 2 seperate maps. The size of the image is seeming to be a problem.

I always use Canon Photostitch - I find it very easy to use - and generally the best of the lot.

No offense ment to the gents above but Panoramafactory has issues, and for what your asking it to do you have to look in a few other places.

First is AutoStitch, You will likely need JPegs. The kind of image you are talking about can be extremely large, You will need to have it set to .25 gigs of ram so that it will force yoru cpu to create more blocks instead of fewer. This will give you the best chance of not getting out of memory errors. Also you will need a HUGE scratch disk space 15-20 gigs free.

Autostitch
http://www.cs.ubc.ca/~mbrown/autostitch/autostitch.html

AutoPano Pro, Autostitch's comercial big badass brother. 10x the power far more versitile, will run you about 120 EU. Save/render the image as a PSD, if you save as a Jpeg it will have to load the images into memory and work form there. You will likely have out of memory errors when producing the image larger than a 25% setting. Rendering in PSD should solve that. *note* my 140 image pano took 5 hours to render with three gigs of ram.

autopano pro

Finally the Fully manual solution to your needs. PTAssembler
This is a time consuming but fully manual and worth while program to know.

PTAssembler, You'll need various other tidbits, and instruction pdf's.

Don't get me wrong it is a fine program. but when multi level pano's are involved it becomes overly complex and a resource hog. It has died on me more times than i can count. While it does a fair job at stitching I think autostitch and auto pano pro do a much better job of stitching95% of the time.

I too have used it for a significant amount of time. My frustrations revolve around poor stitching in some situations compared to AS,APP,&PTA. I also take issue with the program crashing just as it finishes a stitch, which seems to happen way to offten to me. Even with the considerable resources my computer has.

Give AS,APP,and PTA a comparison run.
