Remarks

An edge's strength is the minimum/maximum edge value along the width of the edge (depending on
polarity). This value is a normalized percentage of the maximum pixel value.

Use StrengthTarget to find edges with lower strengths. First, find the edge you want to search for a record
the Strength result value. Next, set the StrengthTarget property to this value. Then set the
ScoreWeightStrength to a higher value than ScoreWeightContrast. This tells the Edge object to look for an
edge with the desired strength and base the score on it.
