Starting from the basic problem of reconstructing a 2dimensional im age given by its projections on two axes, one associates a model of edge coloring in a complete bipartite graph. The complexity of the case with k = 3 colors is open. Variations and special cases are considered for the case k = 3 colors where the graph corresponding to the union of some color classes (for instance colors 1 and 2) has a given structure (tree, vertex disjoint chains, 2factor, etc.). We also study special cases corresponding to the search of 2 edgedisjoint chains or cycles going through speci ed vertices. A variation where the graph is oriented is also presented. In addition we explore similar problems for the case where the under lying graph is a complete graph (instead of a complete bipartite graph).
