# Positional Scoring Methods

You can score an edge pattern candidate based on the position of the edge pattern candidate relative to the center of the projection region you specified for this Caliper tool. The position is defined as the distance between the center and the model origin point within the edge pattern candidate.

If you expect the edge of interest to be a specific distance from the center of the projection region, then you can define an absolute positional scoring method and the raw score will be expressed as an absolute distance in pixels.

If you are using an edge pair model and you would like to consider the variation in position between the edge pattern candidate and the center of the projection region relative to the size of the model, you can define a relative positional scoring method. In this case the raw score will be normalized so that a value of 1.0 means that the distance was equal to the size of the model.
