On Stitching Software

Over the years I tried to optimize my workflow of creating virtual tour spots from fisheye images as well large regular panoramic views using stitching and graphics editing software.
Photoshop is my choice to finetune all panoramic works in terms of color temperature, brightness, contrast, and patching. I use PANO2VR to create flash files and do conversion between various formats.
But what is about stitching software ? I use 3 of them (PTGUI, Autopano, MS ICE). Why this ?
With some panorama images I get different results (mostly in the default mode), while sometimes PTGUI can immediately work out a good result with the source images, Autopano cannot handle it and vice versa.
Sample: PTGUI works

Sample: Autpano fails
I guess the algorithm behind the 2 applications are different.

  • ICE is only suitable for regular (non-fisheye) images. Occasionally its default panorama detection works better.
  • I tried to migrate completely to Linux (Ubuntu) to enjoy the flexibility and speed of Linux systems. While Pano2VR and Autopano have dedicated Linux versions, Photoshop and PTGui dont. You can run PTGui with WINE (a Windows emulator for applications), but to get Photoshop running with WINE requires more experimenting and might not 100% work.
  • I also tried to migrate to GIMP, but after working for 15 years with Photoshop (it is around since 1990 with version 1.0) it is hard to re-adjust. It is free to use and it comes with its features close to Photoshop and certainly will satisfy your standard postprocessing needs.

    Check this blog for CS5 with WINE.
    MS ICE does not work with WINE 1.3 and 2.6.7

    1. Hey Sven, how's life in Singapore?
      You might try tilting up the camera by about 10 degrees. It's not a difficult panorama but I think AP fails because it is trying to stitch the panorama head which is visible in all 4 shots; PTGui could have done the same. As a bonus you'll get better overlap in the zenith this way.
