Claim 1:
2. The system of claim 1, wherein the operations further comprise:
constructing a plurality of quadrilateral candidates based on the plurality of vertical edges and the plurality of horizontal edges, wherein each quadrilateral candidate in the plurality of quadrilateral candidates is constructed using a different subset of edges from the plurality of vertical edges and the plurality of horizontal edges;
evaluating the plurality of quadrilateral candidates based on fitting attributes associated with the plurality of quadrilateral candidates, wherein a fitting attribute associated with each corresponding quadrilateral candidate in the plurality of quadrilateral candidates indicates how well edges used to construct the corresponding quadrilateral candidate fit in the corresponding quadrilateral candidate; and
