You are using a pre-release of Enblend version 4.1. Therefore, your default PSG is NFT, I'm on the development tip and GC is the default here, thus I had to force NFT and you found no differences. Makes sense. > Would it be a solution for me to turn > seam-optimization off by default? Yes, if it cures the problem and you can live with the sub-optimal blend. We have a bug in the seam-line optimizer in Enblend version 4.1. You could either reconfigure your SCM to use the stable branch with hg branch stable-4_1 or download the 4.1pl1 tarball from SF. BTW, Both go with the "old" Boost libraries. > Is there anything I can do to find out what > what causes my black areas? Depends on how masochistic you are. If the packaged version 4.1.1 or switching to the stable branch fixes the bug you could call it a day. Otherwise, use e.g. `--save-masks' or `--optimize --visualize' to find out about the seam lines. More hard core hacking ("We'll take the long way." -- Princess Amidala): recompile Enblend with -DDEBUG_POLYGON_FILL after comprehending what the #define does and where the the heck ",polygon.tif" comes from. > Unfortunately I can't compile the most recent > version off the svn because it depends on some > boost libraries that are newer than the ones > that ship with Debian 6.

My workaround is to pull Boost from their SVN repo, compile it, and point to the in-source-tree directories "b2" instructs me to when re-configuring Enblend/Enfuse. Part of my "reconfigure" script looks something like this: set -a # export all variables ... BOOST_ROOT=<path-to-compiled-boost-svn-directory> CPPFLAGS=-I$BOOST_ROOT LDFLAGS=-L$BOOST_ROOT/stage/lib -Wl,-rpath=$BOOST_ROOT/stage/lib ... ../configure <your-options> -- You received this bug notification because you are a member of Hugin Developers, which is subscribed to Enblend. https://bugs.launchpad.net/bugs/1153546 Title: black artifacts after blending Status in Enblend: New Bug description: I'm frequently getting black artifacts on some blended photos (none or one in small projects, easily 5 to 10 artifacts in projects of more than 100 photos). The occurrence of artifacts does not depend on the output resolution. The shape, however, is dependent on the resolution. Appended are three photos. On my machine blending yields the following output: $ enblend -v -o foo.tif img_7306-73170000.tif img_7306-73170010.tif img_7306-73170011.tif --fine-mask enblend: info: loading next image: img_7306-73170000.tif 1/1 enblend: info: loading next image: img_7306-73170010.tif 1/1 enblend: images do not overlap - they will be combined without blending enblend: use the "-l" flag to force blending with a certain number of levels enblend: info: loading next image: img_7306-73170011.tif 1/1 enblend: info: creating fine blend mask: 1/3 2/3 3/3 enblend: info: optimizing 2 distinct seams enblend: info: Annealing Optimizer, s0: 1/4 2/4 3/4 4/4 enblend: info: Annealing Optimizer, s1: 1/4 2/4 3/4 4/4 enblend: info: Dijkstra Optimizer: s0 s1 enblend: info: using 5 blending level(s) enblend: info: generating Gaussian pyramid: g0 g1 g2 g3 g4 enblend: info: generating Gaussian pyramid: g0 g1 g2 g3 g4 enblend: info: generating Laplacian pyramid: l0 l1 l2 l3 l4 enblend: info: generating Gaussian pyramid: g0 g1 g2 g3 g4 enblend: info: generating Laplacian pyramid: l0 l1 l2 l3 l4 enblend: info: blending layers: l0 l1 l2 l3 l4 enblend: info: collapsing Laplacian pyramid: l4 l3 l2 l1 l0 enblend: info: writing final output The version is $ enblend -V enblend 4.1-700e60bc31b5 Copyright (C) 2004-2012 Andrew Mihal.
