CogCNLSearchEdgeScoreNotComputedException	This result was not created using the NonLinearCNLPAS algorithm.

Remarks

The edge score is the percentage (from 0.0 through 1.0) of the edge pixels in the trained pattern that are also present in the found pattern instance (Nonlinear CNLPAS searches only).

You can use the edge score in conjunction with the AreaScore to determine whether a low overall score was caused by occlusion or clutter.
