	Changed	This event is raised when one or more parts of the object's state may have changed. (Inherited from CogSerializableChangedEventBase.)

The new peak and alley algorithm uses two line segments to detect angle differential on a profile. Think of the line segments as two subway cars moving along the profile. The intersection of the two line segments is equivalent to the pivot point between the two subway cars. As the line segments move along the profile the angle between the lines is measured (at their point of intersection) and when this angle is within the specified thresholds a corner is identified.

1. The profile is resampled to have equal arc length between sample points and gaps in the profile are filled using interpolation.

2. The interpolated points in the gaps are then marked as valid for processing if the gap length is less than or equal to a user specified value, or invalid. The MaxGapToFill is used in this step

3. For each valid point, two lines are fitted around the point using the line length specified by the user. The algorithm determines first if points around a gap can be used, and then if there are enough valid points to fit a line. The center point must be a valid point. LineFitLength, LineFitSpacing, StopLineFitAtGap, and LineFitValidPointFraction are used in this step.

4. Angle differential is computed at each valid point using the line length specified by the user. The algorithm determines first if points around a gap can be used, and then if there are enough valid points to fit a line. LineFitLength, LineFitSpacing, StopLineFitAtGap, and LineFitValidPointFraction are used in this step.

5. Angle differentials that are within the angle thresholds are detected, and at each instance, the corner location is determined by intersecting the 2 line segments around the point. CornerType, MinCornerAngle, and MaxCornerAngle are used in this step.

6. Corners are then sorted and returned to the user. SortType and SortDirectionAngle are used in this step.

7. VisionPro will return a single corner point chosen by the user. CornerSelection is used in this step.

The edge point’s algorithm is quite different and relies on identifying edge points at missing pixel regions after filling gaps smaller than MaxGapToFill.
