# Straddle Scoring Methods

If you are using an edge pair model, you can score edge pair candidates based on whether or not the two edges lie on either side of the center of the projection region. This type of scoring method can be used to find objects defined by a pair of edges that are expected to lie under the center of the projection region. The raw score is returned as 1.0 if the center of the projection region is straddled by the edges, 0.0 if the center of the projection region is not straddled by the edges.
