LineMaxEdgePoint.GradientMagnitude Property

LineMaxEdgePoint GradientMagnitude Property

Cognex VisionPro 9.21 SR1

Gets the gradient magnitude of the edge point. This value is considered the contrast measurement of the edge point.

Return Value

Type: Double

The absolute gradient magnitude.

Remarks

The gradient magnitude is computed using: sqrt(GradientX2 + GradientY2) The Contrast measurement of a line segment is computed using the average GradientMagnitude of all its Inliers.
