Hi, The vertex state space is already restricted to the perpendicular lines as you suggest. When the initial seam line bends, these state space lines tend to intersect, which leads to geometrically uninteresting solutions where the seam line doubles back on itself. Addressing this issue would

Hi, The initial seam line generation I wrote is a nearest feature transform based on voronoi transformation (Breu et al). There is a bug in my implementation. I have a half-complete repair that is not checked in yet, and Christoph has a repair in his staging branch. I intend to replace the

Thanks for trying to help, butI'm still confused. If you place the initial seam in the middle and I assume you mean horizontal center at the top, you would get a distance to the left image's boundary (indicated by the red line) of zero while still having a small distance to the right
