It is not only the the closed contour (where there is a bug as shown) http://wiki.panotools.org/Enblend_Testcase_2008-05-02 but one should think about overlap areas where the bordering is not just images A-B but maybe A-B-A-B or even A-B-A-B-A-B when one loops around the bounding line. One needs two or even three seam lines, and there is a choice of topology. Computing a nearest neighbour mask based on raster representation does not run into such kind of problem, of course. > - How to avoid geometrically uninteresting seam solutions, such as > seam lines that double back on themselves. If one crops the stitching output, then topologically the blend area may be bordered by image A or image B, but third possibility is that the crop line is a border as well. No problem for a bitmap-based nearest neighbour algorithm (again), but in principle one has the freedom to start the seam line, anywhere along the border. Of course one wants to slightly prefer a mid-point start. http://wiki.panotools.org/Enblend_Testcase_2008-05-18 shows where a different seam line start would be beneficial. One more thing. For debugging, for development I would like --save-masks --load-masks --visualises commands that save all masks and seam line visualisations. At the moment files only from the last blend step are surviving (the previous versions are overwritten), and a standard stitch usually uses more than 2 images.
