"WebYou'd like to match each point from db1 with a point from db2 such that the "error" of the matching, e.g. sum of distances, will be minimized. A simple greedy approach for solving this might be to generate an m x n matrix with the distances between each pair of coordinates, and sequentially select the closest match for each point.
