About Enblend:

Enblend is a postprocessing tool for creating panoramic images. After you
align image features using a program like Hugin, there are often
photometric problems that lead to ugly seams in the final composite.  
Enblend blends away these seams using a multiresolution spline. This
technique gives good results on both low spatial frequency objects (sky
and clouds) and high spatial frequency objects (trees and houses).

Changes from version 0.9:

 - Replaced erosive thinning algorithm for mask creation with a much faster
   nearest feature transform.

 - Reduced memory requirements. Enblend now swaps most of its data to disk
   as temporary files. Enblend also calculates the region of pixels that
   are involved in each blending step and only does math on those pixels,
   improving speed and memory usage.

 - Added an option to limit the number of blending levels used.
   This can reduce memory usage and improve speed (at a loss of quality).

 - Added an option to blend around the -180/+180 degree boundary.
   This is useful for full-360 panoramas. There is still an open issue
   as to how to handle the zenith and nadir.
