On-screen stitched image VERY different from saved .JPG file RRS feed

  • General discussion

  • I attempted to stitch together these three images:

     .. creating this ICE project file in the process:

    Here is a screenshot of what ICE showed after compositing the images:

    .. And here is what ICE actually saved to a .JPG file!

    This behavior persists between ICE 1.4.3 and 1.4.4, and after re-loading 1.4.3.

    Looks like a bug. However, this occurs on only one of the two computers where we've tried it; on the second computer, the on-screen display does match the final saved .JPG file on disc. (Okay, it's STILL a bug, but maybe one explainable by some other software installed on the first PC).

    The first PC runs Windows 7 Professional 64-bit. The second PC runs Windows 7 Ultimate 64-bit. Both are managed directly by me. There is different software on the two machines - for example, PC1 is using Office 2007, while PC2 is using Office 2010; and some programs are on one but not the other, etc.

    Any ideas what would cause ICE to show one thing and save another? (Not that even the image shown was quite right - look closely and you'll see that my wife and her bicycle have had a science-fiction-ish merger in the on-screen image... sigh). Cool tool, obviously not perfect :-}

  • This is a known issue with ICE.  We should list it as such.

    The preview step uses a quicker rendering code path than the export step.  The intent is to quickly get a preview image on the screen so that you can set the horizon and crop rectangle, before doing the full-res. export.  Part of the stitching process is "ideal seam selection" which may behave differently on full-res export vs. low-res preview.  This is why you are seeing different results.  This is on the list of things to fix but for now is a quirk in the program.  The reason you are seeing different machines behave differently is that the size of the preview is dependent on the size of the ICE display window.

  • Not sure how to remedy this, but the wonderful composite panorama made from 4-5 original images looks perfect on the ICE screen as I view it.  Saving the image (e.g., Export to Disk) produces a jpg that now has an overlap error or shadow, etc., that's simply not on the screen.

    Any hints what I'm doing incorrectly or the solution?

  • Just experienced the same issue with various panoramas, from a couple of photos on a panorama, up to 12 photos. The composition in ICE looks perfect, as the exported JPG shows seams between some pictures, and slight offsets.

    Will there be a new ICE build coming out soon, which may have this issue fixed?

  • Problem still exists in version - 25/05/2011.
    Is development dead?

  • Nope, not dead but ignoring the issue.

    See the first reply from Matt Uyttendaele, they know about the “quirk” but prefer to “work” on other things like stitching thousands of images instead of fixing the basics.
