Enblend Project Page

overlays TIFF images so as to make the seam invisible. Works with 8, 16 or 32 bit (HDR floating point) per channel images.

Works as a plug-in for PTGui, hugin, PTMac or PTAssembler or standalone from the command line or by Enblend Front End.

As of version 3.0, enblend now: adjusts the seam line to avoid areas of mismatch between source images such as parallax errors, supports saving and loading masks, and includes various other performance improvements.

enblend is available for Windows and Linux from the above link. Mac OSX version (xblend) is available from Kevin Kratzke

If you are working with multi-row panoramics, (for example three rows of eight pictures each), you can greatly speed up the processing by manually feeding the first row of images (with the -a parameter which assembles non-adjacent images first), then the second row of images, and finally the third row of images. Next, feed these three assembled rows into Enblend again using the -a parameter and you will have a fully blended pano in a fraction of the time.

I have written batch files for the Windows platform that do this automatically. Feel free to email me at markdfink_AT_northernlight_DOT_net if you are interested.

Also, other parameters worth noting are:

  • -w to wrap the blending process around the 360 degree boundary so you don't end up with a harsh transition at the +180 and -180 degree seam.
  • -o to force Enblend to use an output filename of your choice
  • -v to see the details of what is happening rather than staring at a blank screen
  • -l 20 to force enblend to use the maximum number of levels in order to increase the blend area (minimize visible seam lines)

Enblend supports cropped TIFF input files.

If you are trying to run Enblend 3.0 on Windows and are finding that the program returns immediately with no output, you may be attempting to run a version compiled with SSE instructions on a non-SSE-capable CPU (like older AMD CPU's f.e.). You can obtain an non-SSE binary for Enblend from Sourceforge.

However, it could be that this version still doesn't run as discussed on [1] (problem) and [2] (solution). If so there is a patched version available at http://alto.anu.edu.au/~wpc/private/enblend/enblend-3.0-cyg.zip
