Dear all, I recently discoverd the graph-tool library so first of all congratulation for this development and the nice documentation. As a non "graph" guy I'm currently facing some trouble trying to adapt an energy minimization problem using the boykov_kolmogorov_max_flow function. The goal is to reproduced the work of this paper <https://www.cis.uab.edu/kddm/seminar_home/Lin_Sept25_tree-camera-ready.pdf> (page 3) which uses the max flow function on an 8 connected image where each pixels are discribed by a discrete value (0 or 1) and a probability. I'm still wondering what's the best way to create an 8-connected graph from an array and how to deal with the dual description of the pixels. I some of you have some tips to share, i would gladely listen to them. Thanks in advance,
